Php Cannot Get Connection To Blocking Mode

The PHP bug is triggered only if host is remote. –Mikko Rantalainen Sep 2 '13 at 8:18 I get this issue on localhost connections as well.

With pgsql.auto_reset_persistent enabled, each time pg_pconnect() is being called, connection link is checked, if it is still valid.

With one of my hosted sites, users are sporadically receiving the following error, 'error: the database connection failed'.

Thedatabase link is removed anyway from the list of persistentconnections, due to the "return -1;" directly afterwards.I am aware that there are other solutions, like adjusting"error_reporting" not to include E_NOTICE, or Thedatabase link is removed anyway from the list of persistentconnections, due to the "return -1;" directly afterwards.I am aware that there are other solutions, like adjusting"error_reporting" not to include E_NOTICE, or Basically it could occur in scripts that would normally notcause an error at all.
