build(deps): bump github.com/lib/pq from 1.12.0 to 1.12.3

[dependabot]

Bumps github.com/lib/pq from 1.12.0 to 1.12.3.

Release notes

Sourced from github.com/lib/pq's releases.

v1.12.3

• Send datestyle startup parameter, improving compatbility with database engines that use a different default datestyle such as EnterpriseDB (#1312).

#1312: lib/pq#1312

v1.12.2

• Treat io.ErrUnexpectedEOF as driver.ErrBadConn so database/sql discards the connection. Since v1.12.0 this could result in permanently broken connections, especially with CockroachDB which frequently sends partial messages (#1299).

#1299: lib/pq#1299

v1.12.1

• Look for pgpass file in ~/.pgpass instead of ~/.postgresql/pgpass (#1300).

• Don't clear password if directly set on pq.Config (#1302).

#1300: lib/pq#1300 #1302: lib/pq#1302

Superseded by #1406, which consolidates the open dependabot bumps.

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
