After a test is run, the test harness kills any outstanding connections so
we can drop the test database. Without this, a failing test could leave open
connections dangling causing the drop database to block.
CREATE OR REPLACE FUNCTION _killall_backends(text)
RETURNS Boolean AS $$ import os from signal import SIGTERM
plan = plpy.prepare( "SELECT procpid FROM pg_stat_activity WHERE datname=$1", ['text'] ) success =
True for row in plpy.execute(plan, args): try: plpy.info("Killing %d" % row['procpid'])
os.kill(row['procpid'],SIGTERM) except OSError: success = False
return success
$$ LANGUAGE plpythonu;
