[OUTPUT] statement to ecpg.
|

This includes two new kinds of postmaster processes, walsenders and
walreceiver. Walreceiver is responsible for connecting to the primary server
and streaming WAL to disk, while walsender runs in the primary server and
streams WAL from disk to the client.
Documentation still needs work, but the basics are there. We will probably
pull the replication section to a new chapter later on, as well as the
sections describing file-based replication. But let's do that as a separate
patch, so that it's easier to see what has been added/changed. This patch
also adds a new section to the chapter about FE/BE protocol, documenting the
protocol used by walsender/walreceivxer.
Bump catalog version because of two new functions,
pg_last_xlog_receive_location() and pg_last_xlog_replay_location(), for
monitoring the progress of replication.

Given that undefined types are handled as character strings anyway the type
translation function can simply return the correcponding ECPGt_char type.

For non-SQL3 types ecpg used to return -Oid. This will break if there are
enough Oids to fill the namespace. Therefore we play it safe and return 0 if
there is no Oid->SQL3 tyoe mapping available.

we're not going to support that anymore.
I did keep the 64-bit-CRC-with-32-bit-arithmetic code, since it has a
performance excuse to live. It's a bit moot since that's all ifdef'd
out, of course.

pg_attribute, by having genbki.pl derive the information from the various
catalog header files. This greatly simplifies modification of the
"bootstrapped" catalogs.
This patch finally kills genbki.sh and Gen_fmgrtab.sh; we now rely entirely on
Perl scripts for those build steps. To avoid creating a Perl build dependency
where there was not one before, the output files generated by these scripts
are now treated as distprep targets, ie, they will be built and shipped in
tarballs. But you will need a reasonably modern Perl (probably at least
5.6) if you want to build from a CVS pull.
The changes to the MSVC build process are untested, and may well break ---
we'll soon find out from the buildfarm.

This is more in keeping with modern practice, and is a first step towards
porting to Win64 (which has sizeof(pointer) > sizeof(long)).

at least in some Windows versions, these functions are capable of returning
a failure indication without setting errno. That puts us into an infinite
loop if the previous value happened to be EINTR. Per report from Brendan
Hill.
Back-patch to 8.2. We could take it further back, but since this is only
known to be an issue on Windows and we don't support Windows before 8.2,
it does not seem worth the trouble.

attacks where an attacker would put <attack>\0<propername> in the field and
trick the validation code that the certificate was for <attack>.
This is a very low risk attack since it reuqires the attacker to trick the
CA into issuing a certificate with an incorrect field, and the common
PostgreSQL deployments are with private CAs, and not external ones. Also,
default mode in 8.4 does not do any name validation, and is thus also not
vulnerable - but the higher security modes are.
Backpatch all the way. Even though versions 8.3.x and before didn't have
certificate name validation support, they still exposed this field for
the user to perform the validation in the application code, and there
is no way to detect this problem through that API.

is made, include it in the startup-packet options. This makes it work more
like every other libpq connection option, in particular it now has the same
response to RESET ALL as the rest. This also saves one network round trip
for new applications using application_name. The cost is that if the server
is pre-8.5, it'll reject the startup packet altogether, forcing us to retry
the entire connection cycle. But on balance we shouldn't be optimizing that
case in preference to the behavior with a new server, especially when doing
so creates visible behavioral oddities. Per discussion.

list, minus a few specific words that have to be treated specially. This
replaces a hard-wired list of keywords that would have needed manual
maintenance, and was not getting it. The 8.4 coding was already missing
these words, causing ecpg to incorrectly treat them as reserved words:
CALLED, CATALOG, DEFINER, ENUM, FOLLOWING, INVOKER, OPTIONS, PARTITION,
PRECEDING, RANGE, SECURITY, SERVER, UNBOUNDED, WRAPPER. In HEAD we were
additionally missing COMMENTS, FUNCTIONS, SEQUENCES, TABLES.
Per gripe from Bosco Rama.

This is a preparatory patch for allowing a dynamic cursor name be used in the
ECPG grammar.
Author: Zoltan Boszormenyi
|

The main motivation for this is that it's required for Informix compatibility
in ECPG.
This patch makes the ECPG and core grammars a bit closer to one another for
these productions.

it works just as well to have them be ordinary identifiers, and this gets rid
of a number of ugly special cases. Plus we aren't interfering with non-rule
usage of these names.
catversion bump because the names change internally in stored rules.
