Re: [HACKERS] backend unstable, \d broken, groups broken was CVS 3-22-99 \d broken?

Sounds like you've hit some kind of platform-specific breakage, then.

I'd suggest chasing the \d failure, simply because that's apparently
the easiest thing to reproduce. Look at the source code for psql.c,
and try issuing by hand the same queries it uses to obtain the system
table info for \d. Use a debugger to look at the data coming back
from the backend during \d --- in other words, is the lossage in psql
or in the backend? Most likely it's the backend but you ought to make
sure.

I'm not enough of a backend guru to suggest where to look for the fault
inside the backend... anyone?

You mean no postmaster process running. Is there a corefile? (The
postmaster would drop core in the directory you started it in, IIRC;
or it might be the top /usr/local/pgsql/data/ directory.) If so,
what backtrace do you get from it?
