Sounds like a plan - but I can't seem to create a function - can
anyone tell me what I'm doing wrong? A brief check of the archives
didn't turn up any hints...
Solaris 2.6, Postgresql 7.0.1, Perl 5.6, gcc 2.95.2.
After compiling and installing with
./configure --with-perl --without-tcl
psql=# CREATE FUNCTION pltest(VARCHAR) RETURNS VARCHAR AS
'return $_[0]' LANGUAGE 'plperl';
ERROR: Unrecognized language specified in a CREATE FUNCTION:
'plperl'. Recognized languages are sql, C, internal and the created
procedural languages.
Can I check for the presence of a .so somewhere? It seems to have
installed a couple in $PGSQL/lib:
-rwxr--r-- 1 root other 295784 Aug 21 12:47 plperl.so*
-rw-r--r-- 1 root other 690992 Aug 21 12:47 plpgsql.so
Also,
psql=# select * from pg_language;
lanname | lanispl | lanpltrusted | lanplcallfoid | lancompiler
----------+---------+--------------+---------------+-------------
internal | f | f | 0 | n/a
C | f | f | 0 | /bin/cc
sql | f | f | 0 | postgres
(3 rows)
Do I need to tell postgres to rebuild pg_language, perhaps?
thanks,
