hello, I have interesting problem...
I have stored procedure, which works good, but only if input is "correct". Correct input is, when $1 is id, which exists in table... If I put non exists id, database fall down and restart with this error: server closed the connection unexpectedly This probably means the server terminated abnormally before or while processing the request. The connection to the server was lost. Attempting reset: Failed.
I think, that problem is in line:
FOR tmp_row IN SELECT v_name FROM c_part_cat WHERE v_path @> my_path ORDER BY v_path LOOP
because without them it works well...
Version: 7.4.5 and 7.4.3 (both versions have this problem)
thanx, hlavki
