Why am I getting “An assertion failed!” error while using pgadmin3?

Question

I am using pgadmin3 on ubuntu 15.04 and i don't have any function called GetLongLong() and when I click on continue it terminates the pgadmin3.

Text from backtrace is as follows :

ASSERT INFO:
db/pgSet.cpp(356): assert "col < nCols && col >= 0" failed in GetLongLong().

Are you trying to connect to a Postgres 10 server? PgAdmin 3 doesn't support such connections. To connect to Postgres 10 you'll have to use PgAdmin 4 instead.

I've faced that same problem trying to connect to Postgres 10 server using pgadmin3, version 1.22.2, on Ubuntu 16.04 LTS. It worked with pgadmin 4, version 3.5.
