+# pq - A pure Go postgres driver for Go's database/sql package
+
+[![GoDoc](https://godoc.org/github.com/lib/pq?status.svg)](https://pkg.go.dev/github.com/lib/pq?tab=doc)
+
+## Install
+
+	go get github.com/lib/pq
+
+## Features
+
+* 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`)
+* Package for `hstore` support
+* COPY FROM support
+* pq.ParseURL for converting urls to connection strings for sql.Open.
+* Many libpq compatible environment variables
+* Unix socket support
+* Notifications: `LISTEN`/`NOTIFY`
+* pgpass support
+* GSS (Kerberos) auth
+
+## Tests
+
+`go test` is used for testing.  See [TESTS.md](TESTS.md) for more details.
+
+## Status
+
+This package is currently in maintenance mode, which means:
+1.   It generally does not accept new features.
+2.   It does accept bug fixes and version compatability changes provided by the community.
+3.   Maintainers usually do not resolve reported issues.
+4.   Community members are encouraged to help each other with reported issues.
+
+For users that require new features or reliable resolution of reported bugs, we recommend using [pgx](https://github.com/jackc/pgx) which is under active development.

+# Tests
+
+## Running Tests
+
+`go test` is used for testing. A running PostgreSQL
+server is required, with the ability to log in. The
+database to connect to test with is "pqgotest," on
+"localhost" but these can be overridden using [environment
+variables](https://www.postgresql.org/docs/9.3/static/libpq-envars.html).
+
+Example:
+
+	PGHOST=/run/postgresql go test
+
+## Benchmarks
+
+A benchmark suite can be run as part of the tests:
+
+	go test -bench .
+
+## Example setup (Docker)
+
+Run a postgres container:
+
+```
+docker run --expose 5432:5432 postgres
+```
+
+Run tests:
+
+```
+PGHOST=localhost PGPORT=5432 PGUSER=postgres PGSSLMODE=disable PGDATABASE=postgres go test
+```
