The website link on the right hand side of this Github's project results in a HTTP 404 error.

We need to use distinct "release" for each documents:

• https://arrow.apache.org/flight-sql-postgresql/devel/
• https://arrow.apache.org/flight-sql-postgresql/current/
• https://arrow.apache.org/flight-sql-postgresql/0.1.0/

Other SELECT options will be supported later.

PostgreSQL's TLS related configurations must be used.

We need numbers to evaluate whether the current approach is reasonable.

It seems that Apache Arrow Flight SQL doesn't provide a command that closes the current session explicitly:
https://arrow.apache.org/docs/format/FlightSql.html

In https://lists.apache.org/thread/0w25o85y8vsndz87kpjljxz24x077o3y , using a custom (close) action was suggested.

@lidavidm Is using a custom close action still a suggested approach to close the current session? I have a concern about this approach. If each Apache Arrow Flight SQL server implementation uses different custom close action, users can't use a general Apache Arrow Flight SQL client including ADBC to use Apache Arrow Flight SQL servers. (Users need to implement a custom close action for each Apache Arrow Flight SQL server.)

It's for PMC members who use macOS.

We'll be able to reuse https://github.com/kou/arrow/blob/flight-sql-postgresql/flight-sql-postgresql.md .

It can accept a Flight SQL connection but all functions are not implemented.

Because PostgreSQL uses Meson.

It just connects to Flight SQL adapter for PostgreSQL.

We need to implement authentication feature by ourselves because PostgreSQL's authentication related API is based on the PostgreSQL protocol.

See also: https://git.postgresql.org/gitweb/?p=postgresql.git;a=blob;f=src/backend/libpq/auth.c

We can use it for performance tuning.

Other types will be supported later.

We need to wait for packages jobs to prepare verify RC jobs.

It's uint64_t not uint32_t.

It should use
https://github.com/apache/arrow-flight-sql-postgresql/releases/download/${TAG}/${FILE} not
https://github.com/apache/arrow-flight-sql-postgresql/releases/tag/${TAG}/${FILE}.

We can use constant user and database for now.
