Samuel Stauffer 2daeb8dc5f pgconn: normalize starTLS connection error 
Normalize the error that is returned by startTLS in pgconn.connect. This
makes it possible to determine if the error was a context error.

Jack Christensen df3c5f4df8 Use "Pg" instead of "PG" in new PgError related identifiers 
Arguably, PGError might have been better. But since the precedent is
long since established it is better to be consistent.

James Hartig b1631e8e35 pgconn: add OnPGError to Config for error handling 
OnPGError is called on every error response received from Postgres and can
be used to close connections on specific errors. Defaults to closing on
FATAL-severity errors.

Fixes #1803

Evan Jones 384fe7775c Batch.Queue: document always uses the conn's DefaultQueryExecMode 
The only way to change the query mode used by Batch.Queue and
SendBatch is to use a connection with a different
DefaultQueryExecMode. Add this to the function documentation.

Conn.SendBatch: Move where mode is defined to make this clearer in
the code. I spent time looking for the option that does not exist.

Sam Whited 94e56e61ba Fix usage of logger in stdlib docs 
The documentation previously showed the old way of logging and not the
newer tracer adapter. This patch updates the example to build correctly
with pgx/v5.

Jack Christensen e5015e2fac pgx.Conn.Deallocate uses PgConn.Deallocate 
This uses the PostgreSQL protocol to deallocate a prepared statement
instead of a SQL statement. This allows it to work even in an aborted
transaction.

Jack Christensen 4dbd57a7ed Add PgConn.Deallocate method 
This method uses the PostgreSQL protocol Close method to deallocate a

transaction.

Jack Christensen cf6ef75f91 stdlib: Use Ping instead of CheckConn in ResetSession 
CheckConn is deprecated. It doesn't detect all network outages. It
causes a 1ms delay while it tries to read the connection. Ping incurs a
round trip but that means it is a much stronger guarantee that the
connection is usable. In addition, if the application and the database
are on the same network it will actually be faster as round trip times
are typically a few hundred microseconds.

Jack Christensen 81ddcfdefb Fix spurious deadline exceeded error 
stdlib_test.TestConnConcurrency had been flickering on CI deadline /
timeout errors. This was extremely confusing because the test deadline
was set for 2 minutes and the errors would occur much quicker.

The problem only manifested in an extremely specific and timing
sensitive situation.

1. The watchdog timer for deadlocked writes starts the goroutine to
   start the background reader
2. The background reader is stopped
3. The next operation is a read without a preceding write (AFAIK only
   CheckConn does this)
4. The deadline is set to interrupt the read
5. The goroutine from 1 actually starts the background reader
6. The background reader gets an error reading the connection with the
   deadline
7. The deadline is cleared
8. The next read on the connection will get the timeout error

Jack Christensen 45f807fdb4 Special case the underlying type of []byte 
Underlying types were already tried. But []byte is not a normal
underlying type. It is a slice. But since is can be treated as a scalar
instead of an array / slice we need to special case it.

Jack Christensen 7a2b93323c Prevent prematurely closing statements in database/sql 
This error was introduced by 0f0d236599.
If the same statement was prepared multiple times then whenever Close
was called on one of the statements the underlying prepared statement
would be closed even if other statements were still using it.
