* Fix: Check for nil in defer when sending batch (recover properly from panic)
* Fix: json scan of non-string pointer to pointer
* Fix: zeronull.Timestamptz should use pgtype.Timestamptz
* Fix: NewConnsCount was not correctly counting connections created by Acquire directly. (James Hartig)
* RowTo(AddrOf)StructByPos ignores fields with "-" db tag
* Optimization: improve text format numeric parsing (horpto)

Establishing a Connection
The primary way of establishing a connection is with `pgx.Connect`.
The primary way of establishing a connection is with [pgx.Connect]:
conn, err := pgx.Connect(context.Background(), os.Getenv("DATABASE_URL"))
The database connection string can be in URL or DSN format. Both PostgreSQL settings and pgx settings can be specified
here. In addition, a config struct can be created by `ParseConfig` and modified before establishing the connection with
`ConnectConfig` to configure settings such as tracing that cannot be configured with a connection string.
