than the other, an indexscan-based merge can win by not scanning all
of the other table. Per example from Reinhard Max.
before reporting command-complete message for the final command of a
query string. This way, any errors detected during finish_xact_command
(such as RI violations) will appear to be part of the final command,
rather than coming out after the command is reported complete. This
avoids confusing PQendcopy and other not-overly-bright clients.

Also improve a couple of error messages about inconsistencies.
are now both invoked once per received SQL command (raw parsetree) from
pg_exec_query_string. BeginCommand is actually just an empty routine
at the moment --- all its former operations have been pushed into tuple
receiver setup routines in printtup.c. This makes for a clean distinction
between BeginCommand/EndCommand (once per command) and the tuple receiver
setup/teardown routines (once per ExecutorRun call), whereas the old code
was quite ad hoc. Along the way, clean up the calling conventions for
ExecutorRun a little bit.

7.2 and earlier pg_dump. 7.2.1 and later pg_dump will double-quote mixed
case names in \connect. Once we feel that older dumps are not a problem
anymore, we can revert this change and treat \connect arguments as normal
SQL identifiers.

It gets much easier to generate extra commands now, and one can rest
assured that the extra commands will be properly analyzed/rewritten.
Without this patch, if a command produced by transformation tries to
use these static lists their first contents would be lost with
unpredictable results. I know I could fix this by just using nconc()
instead of assignments, but the resulting order of the commands would
not be exactly what one could expect.

hashname() and reduce the penalty incured when NAMEDATALEN is increased.
I posted this to -hackers a couple days ago, and there haven't been any
major complaints. It passes the regression tests. See -hackers for more
discussion, as well as the suggestion from Tom Lane on which this patch
is based.
Unless anyone sees any problems, please apply for 7.3.

DATABASE; also make it use SET SESSION AUTHORIZATION commands rather than
\connect commands. This makes it possible to restore databases belonging
to users who do not have CREATEDB privilege. It should also become at
least somewhat feasible to run the restore script under password
authentication --- you'll get one superuser password prompt per database,
rather than a large number of challenges for passwords belonging to
varying unspecified user names.
