I have a problem with my PostgreSQL 8.3.4 installation.
We had some problems with our storage subsystem and it seems
postgresql suffered a little bit from it.
Here are some log excerpts:
When trying to start postgesql:
# /etc/init.d/postgresql-8.3 start
Starting PostgreSQL 8.3 database server: main* Removed stale pid file.
The PostgreSQL server failed to start. Please check the log output:

I think the index is not a system index.
But when I tried to start Postgresql in single-user mode to be able to
repair this index i am getting the mentioned SIGSEGV.
Here is the last part of the strace output:
Here is the gdb output:
Program received signal SIGSEGV, Segmentation fault.

Its a debian, and I think there are no debug symbols in the package
(gdb announces some "no debugging symbols found")
Anyone knows what to do?
Thanks in advance,
