Apologies for the rather naive question. I have a psql migration script to call a looping procedure which commits batches of data along the following lines: set search_path = a, b c; \set AUTOCOMMIT on -- call procedure with nested transactions CALL c.pr_my_procedure(debug=>true); I'm trying to migrate this to a programme using the golang pgx module to exec this code on a large number of databases in parallel. There doesn't seem an obvious way of setting autocommit outside of psql, so the equivalent of conn.Exec(context.Background(), "set search_path = a, b c; set AUTOCOMMIT on; CALL c.pr_my_procedure(debug=>true);") fails with ERROR: syntax error at or near "ON" while conn.Exec(context.Background(), "set search_path = a, b c; CALL c.pr_my_procedure(debug=>true);") fails with ERROR: invalid transaction termination How should I set autocommit on? The "Create Procedure" docs at https://www.postgresql.org/docs/current/sql-createprocedure.html don't seem to mention autocommit. Rory
