There is nothing in what you report to indicate that there is anything
wrong with the server at all. It looks to me like you have client
programs that are issuing bogus queries, but you need to go fix that
on the client side; it's hardly the server's fault.

Syntax error in client-generated query.

Ditto.

Internal problem in PHP (possibly an indication of code that isn't
checking for query failure).

Unnecessary intervention.

You've got some client process that is connecting and issuing a bogus
query once a minute. The first of these messages occurred because it
tried to do so while the database was still restarting. However, the
restart clearly completed without incident, because we see fresh backend
sessions running to issue the later messages.

Nothing on the postgres side, AFAICS. Possibly you need a PHP guru.
You might also try turning on log_statement so you can see the full text
of the invalid SQL commands in the log; that might help track down the
source.
