when I'm trying to execute the following command with a java.sql.Statement
an error occurs:
CREATE OR REPLACE FUNCTION test(text) RETURNS void AS $$ DECLARE tmp text;
BEGIN tmp := 'test'; END; $$ LANGUAGE plpgsql;
org.postgresql.util.PSQLException: ERROR: unterminated dollar-quoted string
at or near "$$ DECLARE tmp text"

The command: CREATE OR REPLACE FUNCTION test(text) RETURNS void AS ' DECLARE
tmp text; BEGIN tmp := "test"; END; ' LANGUAGE plpgsql;
works fine, also creating the function with php (phppgadmin). I have the
latest version of the jdbc driver.
Is this a bug, or my fault?
Thanks,

I'm pretty sure the jdbc driver doesn't understand dollar-quoting yet.
(Patches to fix this would be gratefully accepted no doubt...)

TIP 9: In versions below 8.0, the planner will ignore your desire to
choose an index scan if your joining column's datatypes do not
match

This is a known bug in the JDBC driver. It does not support dollar
quotes.

TIP 6: explain analyze is your friend
INSERT INTO table VALUES ($t$some text$t$)
(or UPDATE ...)
passed to the database? In that case dollar quotes are working
definitely.

The JDBC driver executes multiple queries within the same string
(Statement.execute("SELECT 1; SELECT 2")) by splitting them on the
semicolon and executing them separately. So the difference is that your
plpgsql function body has semicolons while your simple example does not.
