Обсуждение: OS/X and PL/PGSQL

I am having a very very odd time with PostgreSQL 7.3.2 and PL/PGSQL.  I
am pretty sure that I have a working install of 7.3.2 and PL/PGSQL.
However, I don't now, for reasons which are not clear. I can create a
new database, and try to add PL/PGSQL to it, and the results are as
follows:

[Robin:~] pramsey% createdb pltest
CREATE DATABASE
[Robin:~] pramsey% createlang plpgsql pltest
ERROR:  Load of file /usr/local/pgsql/lib/plpgsql.so failed: no error
message available
createlang: language installation failed

The library file *does* exist, and the permissions are all set so that
the library is readable.  Any ideas on this one?

Not sure if this is true on OS/X, but on many Unixen, the dynamic loader
will write failure messages on stderr that are much more useful than the
narrow-band error indicator returned to the calling code.  Make sure
your setup is sending postmaster stderr to a file, not /dev/null, and
then look in the file to see if this produces any interesting output.

Or maybe it's because of this?

char *
pg_dlerror(void)
{
        return "no error message available";
}

Hmm, that's sure not helping any :-(.  But I don't think it invalidates
my suggestion to look at stderr.

Paul, did you find what was the significant difference between your
boot-time and hand-started postmaster environments?

No, unfortunately it is one of those reboot, reinstall, kinds of
things.  I recompiled and reinstalled PgSQL. Stopped it. Ran it from
command prompt. It worked. That was when I emailed you. But then I
rebooted, so it started via the system scripts. Still worked. I wish I
knew what it was. I assume at some point it'll stop working again :)

Thanks guys!

Paul
