I'm trying to connect pgAdmin Version 4 to an existing Postgres instance. Previously I was using pgAdmin 3 and it was working fine. I'm not sure what I might be doing wrong. I have the following configurations:

Not sure what I could be missing.

I get the error below:

Unable to connect to server:

ERROR: unrecognized configuration parameter "bytea_output"

  • What is your Postgres version? –  Oct 24 '16 at 06:51

    I guess pgAdmin 4 simply doesn't support such an outdated (and unsupported) version. `bytea_output` was introduced in 9.0 (which is also no longer maintained) –  Oct 24 '16 at 07:02

PostgreSQL 9.0 and earlier are not supported by pgAdmin 4.

Unfortunately that is not documented yet, but you can find it in this and this bug report (requires a PostgreSQL community account):

Sorry, we're only building support for 9.1 and later (the currently supported releases). pgAdmin 3 can still be used with earlier versions.

  • please support postgresql shipped with centos 6.x. maybe there is a workaround? – Superbiji Oct 28 '16 at 06:44
  • If you want that request to reach the authors of pgAdmin, you should direct it to the [support mailing list](https://www.pgadmin.org/support/list.php). – Laurenz Albe Oct 28 '16 at 06:48

pgAdmin4 supports Postgres9.2 & above version.
