|
|
|
|
* Enhancements

* Postgrex.INET will add a /32 netmask to an IPv4 address and a /128 netmask to an IPv6 address during encoding where `netmask: nil`. When decoding, a /32 netmask (for IPv4) or /128 netmask (for IPv6) will be removed, resulting in `netmask: nil` for the struct
|
|
* Add `:disconnect_on_error_codes` which allows Postgrex to automatically disconnect and then reconnect on certain errors. This is useful when using Postgrex against systems that support failover, which would emit certain errors on failover. This change allow those errors to be recovered from transparently

|
|
* Postgrex.Time, Postgrex.Date and Postgrex.Timestamp were deprecated and now have been effectively removed
|
|
* `Postgrex.execute/4` now always returns the prepared query
|
|
