Still have problems connecting to Localhost...

Thanx for solution with "load libpgtcl.so"...

 

but now I have the other problem when I try to connect to the localhost server (with libpgtcl) I get the answer:
"Connection to database failed

 User authentication failed"...

 

  I verified and the server is running with the -i option (it's OK) , and connections from other machines to the server work fine too.

  But when try to use libpgtcl to local connections I get errors... Running psql localy works fine too, but with the options:

" psql -h localhost -u template1 "

I received the error:

"Connection to database 'template1' failed
