This patch adds --with-reports-host configure option, which sets the
REPORTS_BASE_URL constant. The default is reports.citusdata.com.
It also enables stats collection in tests.
Sends a request to /v1/releases/latest?flavor=$CITUS_EDITION once a day,
which returns a response similar to {"version": "7.1.0", "major": 7,
"minor": 1, "patch": 0}. Then compares it with current Citus version,
and if the latest release is newer, logs a LOG message.
This includes:
(1) Wrap everything inside a StartTransactionCommand()/CommitTransactionCommand().
This is so we can access the database. This also switches to a new memory context
and releases it, so we don't have to do our own memory management.
(2) LockCitusExtension() so the extension cannot be dropped or created concurrently.
(3) Check CitusHasBeenLoaded() && CheckCitusVersion() before doing any work.
(4) Do not PG_TRY() inside a loop.
Adds ```citus.enable_statistics_collection``` GUC variable, which ```true``` by default, unless built without libcurl. If statistics collection is enabled, sends basic usage data to Citus servers every 24 hours.
The data that is collected consists of:
- Citus version
- OS name & release
- Hardware Id
- Number of tables, rounded to next power of 2
- Size of data, rounded to next power of 2
- Number of workers
