fix(postgresql_ext): Reconnect before upgrade

[jouir]

SUMMARY

The TimescaleDB extension needs a fresh connection at upgrade because the extension might be accidentally loaded. The upgrade procedure recommends using the -X flag of psql to ignore .psqlrc file that might execute some queries and load the extension.

This commit reconnects before performing the extension upgrade to fix the following error:

Traceback (most recent call last):
  File "/tmp/ansible_community.postgresql.postgresql_ext_payload_yi1aki7a/ansible_community.postgresql.postgresql_ext_payload.zip/ansible_collections/community/postgresql/plugins/modules/postgresql_ext.py", line 428, in main

  File "/usr/lib/python3/dist-packages/psycopg2/extras.py", line 146, in execute
    return super().execute(query, vars)
psycopg2.errors.FeatureNotSupported: extension "timescaledb" cannot be updated after the old version has already been loaded
HINT:  Start a new session and execute ALTER EXTENSION as the first command. Make sure to pass the "-X" flag to psql.

@jouir thanks for the contribution! @hunleyd thanks for reviewing!

@jouir could you please backport the changes to stable-2 ? <- the process in the guide is about ansible-core but what you need is to replace devel with main branch in your mind when applying it.
