char(n) (BPCHAR) length fix

The char(n) (BPCHAR) data type now correctly supports values longer than one byte when converting to fixed-width integers or strings (fixes #71, fixes #79, #72).

Fix Numeric String Serialization

Fixes a bug causing NUMERIC string serialization to produce incorrect values when numbers have more than 4 zeroes before or after the decimal place. (#78, fixes #77)

add PostgresData+JSON support

Adds new methods and properties for using the JSON data type. These methods mirror the existing methods for JSONB.

User-defined Enum + Optional Fix

Bound optional values that are nil should no longer result in an unexpected type warning (fixes #74)

PostgresData will now return strings correctly for user-defined types like enums.

Remove BPCHAR to Swift Integer conversion

Removes support for converting PostgresData containing BPCHAR bytes (CHARACTER(n), CHAR, etc) to Swift integers. Postgres CHAR(n) fields may be padded with extra zero-bytes which makes conversion tricky. Since Postgres intends CHARACTER fields to store string values, PostgresData should only support conversion to Swift strings. To store 8-bits natively, use Postgres "char" type (note the quotes).

PostgresNIO 1.0.0 Beta 2.3

Publicize useful PostgresRow properties (#70)

PostgresNIO 1.0.0 Beta 2.2

• Added PostgresConnection.addListener(channel:handler:) (#60)

This method lets you add handlers for LISTEN / NOTIFY messages.

// add notification listener to connection
conn.addListener(channel: "example") { context, notification in
    print(notification) // notification payload
    context.stop() // stop listening
}
// subscribe to notifications on this connection
_ = try conn.simpleQuery("LISTEN example").wait()
// send notification w/ empty payload
_ = try conn.simpleQuery("NOTIFY example").wait()
