Installing PostgreSQL 7.1.2 on SCO Open Server 5.0.5

Hi,

I tried to compile and install PostgreSQL 7.1.2 on SCO Open Server 5.0.5.
Though not stated in doc/FAQ_SCO, it wasn't possible until I disabled shared
library support (configure --disable-shared) and changed some lines in
src/backend/storage/file/fd.c .

Apart from a minor problem with readline (the [1] key on the keyboard didn't
work, so I recompiled without readline) PostgreSQL seems to work now.
Unfortunately PL/pgSQL can't be used (the shared library 'plpgsql.so' is not
built and the static plpgsql.a cannot be used as handler).

Any suggestions how to get PL/pgSQL working?

Thanks
