Error on character 7.

I suspect it only allows one SQL statement to go through and thinks
everything after the BEGIN; is an error.  I thought of creating a
function in pl/pgsql  that would allow me to do this.  Something like
this in postgresql: NOTE:pseudocode
function(sql_statement_1, sql_statement_2){
BEGIN;
sql_statement_1;
sql_statement_2;
COMMIT;
}

And then I'd run that function from access: NOTE:pseudocode

DoCmd.RunSQL "function('UPDATE accounts..WHERE acctnum = 12345',
'UPDATE accounts...WHERE acctnum = 7534')"
