Bug fixes

• Fixed crashes when trying to run certain SHOW commands via the pgwire prepare path. #37891
• Fixed a rare crash ("close of closed channel") that would occur when shutting down a server. #37893
• Previously, due to a bug when estimating result set sizes in the Optimizer, queries involving large INT ranges could result in poor plans being generated. #38039
• NULLs are now correctly handled by MIN, SUM, and AVG when used as window functions. #38357
• Prevented a possible missing row from queries that involved iterator reuse and seeking into the gap between stables bridged by a range tombstone. #37694

Security improvements

• Only check CommonName on first certificate in file. #38166
• Stack memory used by CockroachDB is now marked as non-executable, improving security and compatibility with SELinux. #38134
