Thread: PGXAConnection - equals method returning false

PGXAConnection - equals method is not working. It returns false due to
wrapping connection into Proxy object. Second argument of invoke is not
unwrapped so we have:

unwrapped_connection.equals(wrapped_connection)

Correct implementation can be found in AbstractJdbc23PooledConnection class.
It compares wrapped objects.

Hi,

Yes, I already reported this in 2011:

Hi Florent,

I didn’t know you already reported it. Anyway it might be good to remind Postgres guys about the problem. This issue is
majorand it's really hard to believe that this hasn’t been covered since 2011. I wonder how many developers will waste
theirtime debugging Apache DBCP or other framework, only to find out that issue lies inside JDBC.

Yeah, it's about time we get this fixed.. I created a pull request on
github with Florent's patch: https://github.com/pgjdbc/pgjdbc/pull/125
