Add support for postgres advisory locks

PR Info

This PR adds support for Postgres advisory locks: https://www.postgresql.org/docs/current/explicit-locking.html#ADVISORY-LOCKS

I was considering just adding one advisory_lock function, and instead having:

pub enum PgFunc {
...
  AdvisoryLock(AdvisoryLock)
}

pub enum AdvisoryLock {
    AdvisoryLock,
    AdvisoryLockShared,
    TryAdvisoryLock,
    TryAdvisoryLockShared,
    AdvisoryUnlock,
    AdvisoryUnlockShared,
    AdvisoryUnlockAll,
    AdvisoryXactLock,
    AdvisoryXactLockShared,
    TryAdvisoryXactLock,
    TryAdvisoryXactLockShared,
}

However this felt a bit messy, and breaking with current conventions.

I did some refactor in #1063. Now FunctionCall::new accepts Into, so you can simplify the code a bit.
