Hi listers! I'll start with some details:
select version();
PostgreSQL 8.0.0 on i686-pc-linux-gnu, compiled by GCC gcc (GCC) 3.3.5 (Debian 1:3.3.3-5)
Upon compiling a new function that I was working on, I came across an error:
"could not read block 0 of relation 1663/17239/16709: Bad address" which was being triggered by my trying to compile my function.
The relation in question turned out to be pg_language. I reindexed that table and the "could not read block..." error went away, then I started to get the "...language "plpgsql" does not exist..." (as shown after the following function):
-- note, this is only a test function, but it yields the same error: dev=# create function text() returns void as $$ dev=# begin dev=# return; dev=# end; dev=# $$ language plpgsql; ERROR: language "plpgsql" does not exist HINT: You need to use "createlang" to load the language into the database.
I then issued a "createlang plpgsql <this_db>"
-- checked the pg_language table at this point (which I probably should have done before I went and ran the createlang command)
dev=# select lanname,lanplcallfoid,lanvalidator from pg_language; lanname | lanplcallfoid | lanvalidator --------------------------------------- plpgsql | 17811 | 17812 plpgsql | 17811 | 17812 internal | 0 | 2246 c | 0 | 2247 plperlu | 17808 | 0 plperl | 17808 | 0 sql | 0 | 2248
Apparently plpgsql does exist. It also now had duplicate entries for plpgsql. I replaced the contents of the table with the all of the same values, minus one of the duplicates and reindexed it. I restarted my postmaster, and the missing language error went away.
Now when I am running any function, I am getting: "ERROR: cache lookup failed for language 17813" (or occasionally, 17810 or 17809).
Once I recompile the function, I no longer get that message. Is there anything else that I can check or do to make this stop happening? Or is this a sign of things to come (possible corruption, etc?)
Thanks for any help!
Cheers,
Bricklen
