PGConn - Postgres Connection Utilities

This package provide a simple mechanism to extend the Postgres sql.DB implementation with some additional capabilities:

• The ability to retry initial connection attempts using a simple backoff mechanism. This is useful in scenarios such as starting containerized applications without wanting to worry about start up order.
• Detecting certain classes of connection related errors.
• Reconnecting to the database using retrys and backoff.

Usage

• Use the OpenAndConnect method to instantiate a *sql.DB instance.
• Use IsConnectionError to determine if the error indicates the connection to the database is lost or hopeless, in which Reconnect should be used to reconnect to the database.
