Hi
I have now changed all entries in pg_hba.conf to 'trust'
I have modified the call as suggested by Christian.
When i call the php script from the command line, the dump i made.
When i call it from apache, i get the output
pg_dump: [archiver (db)] connection to database "magnus2" failed:
could not connect to server: Permission denied Is the server running
locally and accepting connections on Unix domain socket
"/run/postgresql/.s.PGSQL.5432"?
But the server is running, because my phpPgAdmin can display the db
data, and because the dump worked when executed from the commandline.
From the file generated by the "echo" command, i know that the user
executing the php script is apache.
This seems not to be a problem with the password, because then it
would already have contacted the server.
So for some reason the user apache can't connect to the server.
(and "apache" seems to be a "virtual" user: even as root you cannot do
'su appache': This account is currently not available.)
Any ideas?
Thank You
jody
