Well, where does that server_version come from?  Try adding this
somewhere to .psqlrc:

select setting as server_version from pg_settings where name =
'server_version' \gset
 
select setting as server_version from pg_settings where name =
'server_version';
┌──────────────────────────────────┐
│          server_version          │
├──────────────────────────────────┤
│ 10.5 (Ubuntu 10.5-1.pgdg18.04+1) │
└──────────────────────────────────┘
(1 row)
 
I use packages from http://apt.postgresql.org/pub/repos/apt/
