The DROP STATISTICS code failed to properly lock the table, leading to ERROR: tuple concurrently deleted when executed concurrently with ANALYZE. Fixed by modifying RemoveStatisticsById() to acquire the same lock as ANALYZE. This function is called only by DROP STATISTICS, as ANALYZE calls RemoveStatisticsDataById() directly. Reported by Justin Pryzby, fix by me. Backpatch through 12. The code was like this since it was introduced in 10, but older releases are EOL.
