This checkin also adds the type map for jdbc3, however currently it is
identical to the jdbc2 mapping.

of Describe on a prepared statement. This was in the original 3.0
protocol proposal, but I took it out for reasons that seemed good at
the time. Put it back per yesterday's pghackers discussion.
|
|
Describe would claim that no tuples will be returned. Only affects
SELECTs added to non-SELECT base queries by rewrite rules. If you
want to see the output of such a select, you gotta use 'simple Query'
protocol.

DestReceiver pointers instead of just CommandDest values. The DestReceiver
is made at the point where the destination is selected, rather than
deep inside the executor. This cleans up the original kluge implementation
of tstoreReceiver.c, and makes it easy to support retrieving results
from utility statements inside portals. Thus, you can now do fun things
like Bind and Execute a FETCH or EXPLAIN command, and it'll all work
as expected (e.g., you can Describe the portal, or use Execute's count
parameter to suspend the output partway through). Implementation involves
stuffing the utility command's output into a Tuplestore, which would be
kind of annoying for huge output sets, but should be quite acceptable
for typical uses of utility commands.

Reorder non-default variable loading until PGDATA is defined.

the column by table OID and column number, if it's a simple column
reference. Along the way, get rid of reskey/reskeyop fields in Resdoms.
Turns out that representation was not convenient for either the planner
or the executor; we can make the planner deliver exactly what the
executor wants with no more effort.
initdb forced due to change in stored rule representation.

which does the same thing. Perhaps at one time there was a reason to
allow plan nodes to store their result types in different places, but
AFAICT that's been unnecessary for a good while.

avoids 'input buffer overflow' failure on long literals, improves
performance, gives the right answer for line position in functions
containing multiline literals, suppresses annoying compiler warnings,
and generally is so much better I wonder why we didn't do it before.

*got* to be pointless.

Only lightly tested as yet, since libpq doesn't know anything about 'em.

Per recent discussion on pgsql-general, this is appropriate for spec
compliance, and has the nice side-effect of easing porting from old
pg_dump files that exhibit the 59.999=>60.000 roundoff problem.

implementation limits, do not issue an ERROR; instead issue a NOTICE and use
the max supported value. Per pgsql-general discussion of 28-Apr, this is
needed to allow easy porting from pre-7.3 releases where the limits were
higher.
Unrelated change in same area: accept GLOBAL TEMP/TEMPORARY as a synonym
for TEMPORARY, as per pgsql-hackers discussion of 15-Apr. We previously
rejected it, but that was based on a misreading of the spec --- SQL92's
GLOBAL temp tables are really closer to what we have than their LOCAL ones.

per report from Olivier Prenant. Also fix off-by-one space calculation
in ReadToc; this woould not have hurt us until we had more than 100
dependencies for a single object, but wrong is wrong.

(agollapudi@demandsolutions.com).
Also applied the RefCursor support patch by Nic Ferrier. This patch allows
you too return a get a result set from a function that returns a refcursor.
For example:
call.registerOutParameter(1, Types.OTHER);
call.execute();
ResultSet rs = (ResultSet) call.getObject(1);

Both plannable queries and utility commands are now always executed
within Portals, which have been revamped so that they can handle the
load (they used to be good only for single SELECT queries). Restructure
code to push command-completion-tag selection logic out of postgres.c,
so that it won't have to be duplicated between simple and extended queries.
initdb forced due to addition of a field to Query nodes.
|
|
Without this fix, CVS tip dumps core when running the regression tests
with geqo_threshold = 2. I would think that a similar patch might be
needed in 7.3, but cannot duplicate the failure in that branch --- so
for now, leave well enough alone.

of extended query features in new FE/BE protocol. TransactionCommandContext
is gone (PortalContext replaces it for some purposes), and QueryContext
has taken on a new meaning (MessageContext plays its old role).

that the types of untyped string-literal constants are deduced (ie,
when coerce_type is applied to 'em, that's what the type must be).
Remove the ancient hack of storing the input Param-types array as a
global variable, and put the info into ParseState instead. This touches
a lot of files because of adjustment of routine parameter lists, but
it's really not a large patch. Note: PREPARE statement still insists on
exact specification of parameter types, but that could easily be relaxed
now, if we wanted to do so.

latter. Fix documentation omissions while at it.

declared without having to write %ROWTYPE. If the declared type of

I had inadvertently omitted it while rearranging things to support
length-counted incoming messages. Also, change the parser's API back
to accepting a 'char *' query string instead of 'StringInfo', as the
latter wasn't buying us anything except overhead. (I think when I put
it in I had some notion of making the parser API 8-bit-clean, but
seeing that flex depends on null-terminated input, that's not really
ever gonna happen.)

test in there...

in all cases, leaked TopMemoryContext memory in others. Make the
interaction between SetClientEncoding and InitializeClientEncoding
cleaner and better documented. I suspect these changes should be
back-patched into 7.3, but will wait on Tatsuo's verification.

as the correct user, not only query execution. Per report from Sean
Chittenden.

implemented yet though --- the backend always sends zeroes, and libpq
just throws away the data.)

initial values and runtime changes in selected parameters. This gets
rid of the need for an initial 'select pg_client_encoding()' query in
libpq, bringing us back to one message transmitted in each direction
for a standard connection startup. To allow server version to be sent
using the same GUC mechanism that handles other parameters, invent the
concept of a never-settable GUC parameter: you can 'show server_version'
but it's not settable by any GUC input source. Create 'lc_collate' and
'lc_ctype' never-settable parameters so that people can find out these
settings without need for pg_controldata. (These side ideas were all
discussed some time ago in pgsql-hackers, but not yet implemented.)
