48d27a9fff Add PrepareConn hook, which extends BeforeAcquire's behavior to allow canceling the instigating query 
- BeforeAcquire now marked as deprecated, and re-implemented in terms of PrepareConn
- PrepareConn now takes precidence over BeforeAcquire if both are provided
- New tests added, so both old and new behavior are tested
- One niggle: AcquireAllIdle does not return an error, so the only recourse
  that seems reasonable when PrepareConn returns an error in that context,
  is to destroy the connection.  This more or less retains the spirit of
  existing functionality, without changing the public API of that method.
  Although maybe an error-returning variant would be a useful addition as
  well.

a966716860 Replace DSN with keyword/value in comments and documentation 
The term DSN is not used in the PostgreSQL documentation. I'm not sure
why it was originally used. Use the correct PostgreSQL terminology.

e665f74c99 fix TestPoolBackgroundChecksMinConns and NewConnsCount 
Previously it was checking TotalConns but that includes ConstructingConns.
Instead it should directly check IdleConns so the next Acquire takes one of
those and doesn't make a 3rd connection. The check against the context was
also wrong which prevented this from timing out after 2 minutes.

This also fixes a bug where NewConnsCount was not correctly counting
connections created by Acquire directly.

Fixes #1690

c513e2e435 Fix: pgxpool: background health check cannot overflow pool 
It was previously possible for a connection to be created while the
background health check was running. The health check could create
connection(s) in excess of the maximum pool size in this case.

05440f9d3f Drastically increase allowed test times for potato CI 
The context timeouts for tests are designed to give a better error
message when something hangs rather than the test just timing out.
Unfortunately, the potato CI frequently has some test or another
randomly take a long time. While the increased times are somewhat less
than optimal on a real computer, hopefully this will solve the
flickering CI.
