* Add nil check for GlobalConfig in newRefreshConnectionState
Fixes#4779: nil GlobalConfig causes panic in newRefreshConnectionState
Changes:
- Add nil check for GlobalConfig in newRefreshConnectionState before SetUserSearchPath
- Add nil check in getDefaultSearchPath to handle nil GlobalConfig gracefully
- Test now passes instead of panicking with nil pointer dereference

* Add test for #4792: customSearchPath data race
This test demonstrates the data race on the customSearchPath slice when
accessed concurrently from multiple goroutines without synchronization.

* Fix#4792: Add mutex protection for customSearchPath slice
The customSearchPath slice was being accessed concurrently from multiple
goroutines without synchronization, causing data races. This fix adds a
dedicated mutex (searchPathMutex) to protect all reads and writes to the
customSearchPath and searchPathPrefix fields.
Changes:
- Added searchPathMutex field to DbClient struct
- Initialize searchPathMutex in NewDbClient constructor
- Protected all customSearchPath writes in SetRequiredSessionSearchPath
- Protected all customSearchPath reads in GetRequiredSessionSearchPath
- Protected all customSearchPath reads in GetCustomSearchPath
- Fixed logging in ensureSessionSearchPath to use already-fetched value
- Updated test to initialize searchPathMutex for proper testing

* Add test for #4809: BeforeClose should handle nil sessions map
This test verifies that the BeforeClose callback checks if c.sessions map
has been nil'd by Close() before attempting to delete from it.
The test fails as expected without the fix, proving the bug exists.

* Fix#4809: Add nil check in BeforeClose for sessions map
Add nil check in BeforeClose callback before accessing c.sessions map.
This prevents panic when the callback executes after Close() has nil'd
the map.

* Add tests demonstrating bug #4793: Close() sets sessions=nil without mutex
These tests demonstrate the race condition where Close() sets c.sessions
to nil without holding the mutex, while AcquireSession() tries to access
the map with the mutex held.
Running with -race detects the data race and the test panics with
"assignment to entry in nil map".

* Fix#4793: Protect sessions map access with mutex in Close()
Acquire sessionsMutex before setting sessions to nil in Close() to prevent
data race with AcquireSession(). Also add nil check in AcquireSession() to
handle the case where Close() has been called.
This prevents the panic "assignment to entry in nil map" when Close() and
AcquireSession() are called concurrently.

* Add test for #4808: Race condition on disableTiming field
Add test that verifies disableTiming field uses atomic.Bool instead of
plain bool to prevent race conditions.
The test checks that:
- disableTiming is declared as atomic.Bool
- shouldFetchTiming() uses atomic Load()
- getQueryTiming() uses atomic Store() operations
- Direct assignments that cause races are not present
This test will fail until the implementation is fixed.
* Fix#4808: Use atomic.Bool for disableTiming to prevent race condition
* pluginmanager.State.verifyRunning() now checks the process corresponding to the pid is a plugin manager process
pluginmanager.State.kill() deletes the plugin manager state file even if the process is not found
- JSON output format has changed to move the rows to under a `rows` property, with timing information under the `metadata` property
- Update timing display to show rows returned and rows fetched, as well as adding verbose mode which lists all scans
- Use enums for output mode and timing mode - timing is now either `on`, `off` or `verbose`
- Bugfix: ensure error is returned from ExecuteSystemClientCall. Closes#4246
* Add function to clear connection cache.
* Update FDW to v1.9.0 - Add ability to clear connection cache by inserting into settings table.
* Update plugin sdk to v5.6.1
* fix listen unit tests
