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? – a_horse_with_no_name
@a_horse_with_no_name Its version 8.4 – kya
I guess pgAdmin 4 simply doesn't support such an outdated (and unsupported) version. bytea_output was introduced in 9.0 (which is also no longer maintained) – a_horse_with_no_name

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.

pgAdmin4 supports Postgres9.2 & above version.
