Re: Bugs in Postgres

Thanks for the information Thorsten.

I'm forwarding this message to the "hackers" list for further comment.
afaik, the IPC issue on Solaris is a FAQ, and the fix requires
configuring IPC in the Sun kernel with sufficient size, or starting
Postgres with smaller buffers (see the docs on starting the
postmaster).

The plpgsql function problem sounds like an issue with an index on a
system table, and may have been fixed for the upcoming release, but I
don't recall anything specifically. Perhaps others will recall more
detail.

Regards.
