Log message:
py-asyncpg: updated to 0.16.0

asyncpg v0.16.0:

Behavior Changes
----------------
Pool.close() now waits until all acquired connections are released.
Hence, the below code will now hang indefinitely:
    conn = await pool.acquire()
    await pool.close()
Asyncpg will log a warning if pool.close() takes over 60 seconds to
complete. It is advisable to use asyncio.wait_for() to set a timeout.

Improvements
------------
Add support for reading passwords from .pgpass
Add Connection.is_in_transaction()
Added codec for built-in type tid
Allow setting custom codecs on domains and enumerated types
Allow passing datetime.date instances as timestamp input
Implement support for pool connection rotation

Bug Fixes
---------
Prohibit non-iterable containers to be passed as array input
Decode numeric zeros with correct scale
Fix handling of OIDs >= 2**31
Make Pool.close() wait until all checked out connections are released
Fix type codec cache races
Raise a consistent exception on input encoding errors

Log message:
py-asyncpg: updated to 0.15.0

asyncpg v0.15.0

Behavior Changes
asyncpg no longer uses the common statement cache for explicit
prepared statements, so Connection.prepare() always returns a
new prepared statement

Bug Fixes
Initialize statement codecs immediately after Prepare
Fix server version parsing when it contains trailing data

Log message:
py-asyncpg: updated to 0.14.0

v0.14.0:
Backwards Incompatible Changes:
asyncpg now reports the server version as x.0.y for PostgreSQL 10.0 and later.
This is in alignment with how upstream is interpreting the "minor" version
component now.

Improvements:
Support timeouts in Connection.close() and Pool.release()
Invalidate type cache on schema changes affecting statement result.
A new Connection.reload_schema_state() method.
Add CrateDB detection

Bug Fixes:
Make prepared statement uid generator global
Document pgbouncer-related prepared statement breakage
Fix unaligned access issues in host-network byte I/O on ARM
Fix issues with timetz type I/O
Consistently use postgres/postgres as database/user pair in tests
Fix Range.__hash__()
Guard transaction methods against underlying connection release
