Performing a pg_exec($database,"end") on a connection causes the child pid to exit with a SEGV. This may have something to do with PostgreSQL sending a notice message through libpg.


 In the interactive client, psql, there is normally a NOTICE sent to the client:

 webdb=> commit;
 END
 webdb => end;
 NOTICE:  EndTransactionBlock and not inprogress/abort state
 END
 webdb => \q

...and in the backtrace (from running http -X inside gdb), the last mentioned function is 'defaultNoticeProcessor()':

#0  0x40222ee1 in ?? ()
#1  0x40185605 in ?? ()
#2  0x4018ceb3 in ?? ()
#3  0x4031fd1b in defaultNoticeProcessor () from /usr/local/pgsql/lib/libpq.so.2.0
#4  0x40320cf0 in getNotice () from /usr/local/pgsql/lib/libpq.so.2.0
#5  0x403202ff in parseInput () from /usr/local/pgsql/lib/libpq.so.2.0
#6  0x40320b4e in PQgetResult () from /usr/local/pgsql/lib/libpq.so.2.0
#7  0x40320ca3 in PQexec () from /usr/local/pgsql/lib/libpq.so.2.0
#8  0x40291a4c in php3_pgsql_exec () at functions/pgsql.c:124

All tested scripts worked 100% when I removed the 'BEGIN'/'COMMIT'/'END' pg_exec() statements.
