Thread: pg_hba.conf question

I am trying to run an insert script via a contrab job on linux. I am having
problems figuring out the security. What I need is for the local setting to
allow a connection as the same unix user I am logged in as i.e. postgres.

I noticed that you can't use the 'ident sameuser' with local unix sockets,
what is the method of getting round this as I cant use trust for this
database?

Thanks

ident only works with TCP sockets.  You could require people to connect
to host localhost, ie, use a local TCP connection instead of a Unix
socket.  Set up 127.0.0.1 as ident sameuser and socket connections as
reject in pg_hba.conf.

I have tried entering the following as suggested: -
local        all                                               reject
host         all         127.0.0.1           255.255.255.0       ident
sameuser

I have also tried
local        all                                               reject
host         all         127.0.0.1           255.255.255.0     trust

After trying the usual command %psql dbname to connect I keep getting the
message
No pg_hba.conf entry for host localhost, user postgres, database dbname

Is there something obvious I am missing????

Thanks

Graham

Looks to me like you're trying to connect via Unix-socket.  Try
specifying PGHOST=localhost at the client.

Well , it seems Ur editing wrong file.

If Ur working on postgres 6.5 edit the file pg_hba.conf file in pgsql dir

however if Ur working on postgres 7 edit file pg_hba.conf file in
pgsq/data dir and locate other pg_hba.conf file if exists and rename them.

Check this out.

Regrds,
