Well then I have the other error. With this code:

execute 'select ' || NEW.warn_time_init || '($1)' into bpa using NEW;

I get:

NOTICE: bpa inbound (,now_plus_30)
CONTEXT: SQL statement "select now_plus_30($1)"
PL/pgSQL function "bp_alert_init" line 6 at EXECUTE statement
NOTICE: warn time in input row = ("2012-04-27

CONTEXT: SQL statement "select now_plus_30($1)"
PL/pgSQL function "bp_alert_init" line 6 at EXECUTE statement

********** Error **********

ERROR: invalid input syntax for type timestamp with time zone:

I guess you are right, though. This is the error I have to resolve.

Thx,
