Hi all,

After an installation from CVS tip, I start the postmaster with the
-d(anything) flag. The postmaster starts up normally. I then try to
connect using psql, and either a TRAP is triggered (not using -A 0)
or an invalid cache id is found (using -A 0)

When I start the postmaster without the -d flag, I have no problems
in connecting from psql.

Any ideas?

Regards,
Grant

Now, from another console do : psql -l

The backtrace points the finger at Bruce's recent changes in guc.c:
he is trying to call superuser() before the data is available.  Bruce,
please fix or revert.

OK, I moved superuser() back down to the bottom of the if() statement
tree.  I had moved it up in the patch in hopes of reducing code
duplication, but obviously that didn't work.
