Call nextval first?

Too many quotes?

If you execute that (or a similar command) from psql, you'll get a more
human friendly error message:

repository=# select currval('moduleid_seq');
ERROR:  currval of sequence "moduleid_seq" is not yet defined in this
session

Checking the docs at
http://www.postgresql.org/docs/8.3/interactive/functions-sequence.html

currval
   Return the value most recently obtained by nextval for this sequence   in the current session. (An error is reported
ifnextval has never   been called for this sequence in this session.) Notice that because   this is returning a
session-localvalue, it gives a predictable   answer whether or not other sessions have executed nextval since the
currentsession did. 
 

So, that sequence has not had 'nextval' called on it in this session.
