Hi everyone.
Environment:
OS: UW 713
PG: 7.3.2
I've been banging my head for a few weeks on this one and could'nt find
any answer:
pg_dump is crashing with SIGSEGV before it connects to database.
I've re-compiled with --enable-debug and --enable-cassert and even that
did'nt help.
this is gdb output not showing much:

If I vacuum the databse it starts to work again until the script doing
backup runs then pg_dump crashes again.
This is a test system so databases are not even accessed!
They are pulled from the real server running 7.2.3 with pg_dumpall (the
7.3 one) -h server -c|psql template1
It doesn't seem to be a database issue because it used to crash on another
one.
While I'm at it : what is the procedure to remove template1 and replace it
by template0 after a reload? It doesn't seem right to me that pg_dumpall
replace template1 but maybe I'm wrong on this one.
Thanks for your tim and help
