Connection String Parameters

These are a subset of the libpq connection parameters. In addition, a number of the environment variables supported by libpq are also supported. Just like libpq, these have lower precedence than explicitly provided connection parameters.

See http://www.postgresql.org/docs/9.1/static/libpq-connect.html.

• dbname - The name of the database to connect to
• user - The user to sign in as
• password - The user's password
• host - The host to connect to. Values that start with / are for unix domain sockets. (default is localhost)
• port - The port to bind to. (default is 5432)
• sslmode - Whether or not to use SSL (default is require, this is not the default for libpq) Valid values are:
  • disable - No SSL
  • require - Always SSL (skip verification)
  • verify-full - Always SSL (require verification)

See http://golang.org/pkg/database/sql to learn how to use with pq through the database/sql package.

go test is used for testing. A running PostgreSQL server is required, with the ability to log in. The default database to connect to test with is "pqgotest," but it can be overridden using environment variables.

Example:

PGHOST=/var/run/postgresql go test pq

• SSL
• Handles bad connections for database/sql
• Scan time.Time correctly (i.e. timestamp[tz], time[tz], date)
• Scan binary blobs correctly (i.e. bytea)
• pq.ParseURL for converting urls to connection strings for sql.Open.
• Many libpq compatible environment variables
• Unix socket support

• Notifications: LISTEN/NOTIFY
• hstore sugar (i.e. handling hstore in rows.Scan)

Some of these contributors are from the original library bmizerany/pq.go whose code still exists in here.
