PREPARED STATEMENT - Mailing list pgsql-sql

Hi there,

I want to know that is a posibillity to test if a statement is prepared in
PL/PgSQL.

I have create a function:
.........
PREPARE PSTAT_SAVE_record(INTEGER, INTEGER, DATE, VARCHAR) AS INSERT INTO
table VALUES($1, $2, $3, $4);
.........

When I try to execute it second time I got an error: prepared statement  
'PSTAT_SAVE_record' already exists. How can I avoid this error? is there a
posibillity to test if a statement was prepared before?


Thanks,
Nosy
