You seem to be confused about how to escape characters in URLs. The format is a % followed by exactly two hex digits. In this case, that would give you %2h and %2m, and h and m are not hex characters, so the error message is right. Your input is not valid. > There can be PGconn which have no connhost. > exposed API's PQpass, PQreset->connectDBStart access conn->connhost without > checking whether it is set. Can you provide a concrete test scenario or some test code that fails? connhost is supposed to be getting set in connectOptions2(), which is run (AIUI) when the PGconn is first created. So I think that it will be set in all scenarios of the type you mention, but I might be missing something. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
