I've found minor but annoying issue. With high-latency network (in my case Wi-Fi and server on the opposite side of the Earth) Every, even very light query, takes ~ 2-3 seconds.
Interesting that a main query executes in 150 ms. (and less than 30 ms local on server)
But there are a lot of such queries in pgadmin.log (two queries for every column) --- SELECT format_type(oid,-1) as typname FROM pg_type WHERE oid = 20
SELECT CASE WHEN typbasetype=0 THEN oid else typbasetype END AS basetype
FROM pg_type WHERE oid=20 --- and they take also 150 ms every
So with such queries - common time of rendering ~ 2-3 seconds.
Is it possible to cache this data or request them in advance? I suppose this will increase performance in tenth times.
