Обсуждение: PG_ERROR 42501 permissions error

It never rains but it pours they say.  I am trying to extract (ad
hoc) some data from my production database on the 8.1 service that I
tried to upgrade to 8.4. I am using the same username and password
as is used by a process hosted on the same server as the posgresql
instance.  That process works fine.


However, when I try and connect from another server using those
credentials then I see this in the log file:

I am particularly nonplussed over the 'ERROR:  55P02: parameter
"standard_conforming_strings" cannot be changed' message.  Can
anyone here clue me in as to what I am doing wrong?

8.1 did have a read-only parameter named that; in 8.2 and later it's
a read-write parameter.  Sounds like you're using some client-side
software that's not designed to work against such an old server,
and expects that it can set the value however it likes.
