problem reported a few months ago where a select in a rule was causing an insert statement to return a result set which the code was explicitly prohibiting.

wrapped-around databases. The unvacuumed databases might be fine, or
they might not, but things will definitely not be fine if we remove the
wrong CLOG segments. Per trouble report from Gary Wolfe, 1-Apr-2002.

depend on this rather than the trigger argument strings to locate the
other relation to test. This makes RI triggers function properly in
the presence of schemas and temp tables. Along the way, fix bogus lack
of locking in RI triggers, handle quoting of names fully correctly,
compute required sizes of query buffers with some semblance of accuracy.

path. The default behavior if no per-user schemas are created is that
all users share a 'public' namespace, thus providing behavior backwards
compatible with 7.2 and earlier releases. Probably the semantics and
default setting will need to be fine-tuned, but this is a start.

2) Implement some options for SQLGetDescField().
3) Handle *Inifinity* timestamp for SQL_C_CHAR type output.
4) Separate Unicode conversions from common implementations.
5) Improve internal parse_statement() function.

catalog namespace. This will not do as a production solution because
the interpretation of RI trigger arguments will vary depending on the
current namespace search path. I'm just putting it in so that the RI
regression tests don't fail while schema development proceeds. We
must find a better answer before 7.3 can be released.

consistency with renameatt.

temp table entries in pg_class have the names the user would expect.

sequence functions how to cope with qualified names. Same code is
also used for int4notin, currtid_byrelname, pgstattuple. Also,
move TOAST tables into special pg_toast namespace.

support: drop, alter, rename commands work for tables in non-default
namespaces.

1) Prepare to separate 4 kinds of Descriptor handles.
2) Detect the transaction status more naturally.
3) Improve Parse Statement functionality for the use
of updatable cursors.
4) Improve updatable cursors.
5) Implement SQLGetDescField() and improve SQLColAttribute().
6) etc.

also fixed a NPE when calling the next() method on a result set after the
connection or resultset has been closed. (bug reported by Hans Deragon)

path yet, and not all operations work yet on tables outside the system
namespace.

Also, fix debug logging of parse/plan trees so that the messages actually

addRangeTableEntry calls. Remove relname field from RTEs, since
it will no longer be a useful unique identifier of relations;
we want to encourage people to rely on the relation OID instead.
Further work on dumping qual expressions in EXPLAIN, too.

necessary no matter what in the schema environment, and simply getting
rid of the name-based interface entirely seems like the best way.

the parsetree representation. As yet we don't *do* anything with schema
names, just drop 'em on the floor; but you can enter schema-compatible
command syntax, and there's even a primitive CREATE SCHEMA command.
No doc updates yet, except to note that you can now extract a field
from a function-returning-row's result with (foo(...)).fieldname.

these versions adhere to the backend protocol better than previous version
fixes problem when an error occurs on the backend, and the connection is still used
previous versions were throwing an exception half way through the protocol, leaving it
indeterminate.

QueryExecutor. This includes:
1) only exit after we receive a 'Z' packet
2) append error messages to a buffer and throw the exception at the end

StartupPacket
* Introduces a new class, StartupPacket.
* Moves a lot of constants from Connection to StartupPacket.
* Makes two instance variables in Connection into locals.
