Bump asyncpg from 0.21.0 to 0.22.0

[dependabot-preview]

Bumps asyncpg from 0.21.0 to 0.22.0.

Release notes

Sourced from asyncpg's releases.

v0.22.0

A new asyncpg release is here.

Notable additions include Python 3.9 support, support for recently added PostgreSQL types like jsonpath, and last but not least, vastly improved executemany() performance. Importantly, executemany() is also now atomic, which means that either all iterations succeed, or none at all, whereas previously partial results would have remained in place, unless executemany() was called in a transaction.

There is also the usual assortment of improvements and bugfixes, see the details below.

This is the last release of asyncpg that supports Python 3.5, which has reached EOL last September.

Improvements

• Vastly speedup executemany by batching protocol messages (#295) (by @fantix in 690048db for #295)

• Allow using custom Record class (by @elprans in db4f1a6c for #577)

• Add Python 3.9 support (#610) (by @elprans in c05d7260 for #610)

• Prefer SSL connections by default (#660) (by @elprans in 16183aa0 for #660)

• Add codecs for a bunch of new builtin types (#665) (by @elprans in b53f0384 for #665)

• Expose Pool as asyncpg.Pool (#669) (by @rugleb in 0e0eb8d3 for #669)

• Avoid unnecessary overhead during connection reset (#648) (by @kitogo in ff5da5f9 for #648)

Fixes

• Add a workaround for bpo-37658 (by @elprans in 2bac166c for #21894)

• Fix wrong default transaction isolation level (#622) (by @fantix in 4a627d55 for #622)

• Fix set_type_codec() to accept standard SQL type names (#619)
