…ion time The connection acquisition timeout must account for the whole acquisition execution time, whether a new connection is created, an idle connection is picked up instead or we need to wait until the full pool depletes. In particular, the connection acquisition timeout (CAT) has precedence over the socket connection timeout (SCT). If the SCT is set to 2 hours and CAT to 50ms, the connection acquisition should time out after 50ms (as usual, these evil cats win), even if the connection is successfully created within the SCT period. Note: if SCT is larger than or equal to CAT, a warning should be issued, as this is likely a misconfiguration (and big SCT values won't have any effect on connection acquisitions anyway).
