I found out how to resolve this problem, yet it does not explain why it
happens anyway!
I had postmaster started with this script:
unlimit
postmaster -D/usr/local/pgsql/data -B 256 -i -o "-e -S 8192" >>
/usr/local/pgsql/errlog 2>&1 &
Removing all the parameters to postmaster
postmaster -D/usr/local/pgsql/data -i -o "-e" >> /usr/local/pgsql/errlog 2>&1 &
made it work....
Perhaps some memory management problem? I guess the -S option is the culprit
here, but this machine has 256 MB RAM and actually never swaps (yet).
Hope this helps somehow.
