While looking into converting pgssEntry->mutex to an LWLock (per a
suggestion elsewhere [0]), I noticed that pg_stat_statements uses
"volatile" quite liberally. IIUC we can remove these as of commit 0709b7e
(like commits 8f6bb85, df4077c, and 6ba4ecb did in other areas). All of
the uses in pg_stat_statements except those added by commit 9fbc3f3 predate
that commit (0709b7e), and I assume commit 9fbc3f3 was just following the
examples in surrounding code.
Am I missing something? Or can we remove these qualifiers now?
