perf(pglite): keep pooled connections idle instead of churning them

Browse Source 
database/sql keeps only 2 idle connections by default, so with 4 open
the pool closed and reopened connections constantly: about 225
Terminate+handshake cycles per minute during a scan on roy. Every
handshake goes through the single backend, and the first query after a
handshake is where the lost replies were seen.
