github.com/jackc/pgx/v5

• Support sslnegotiation connection option (divyam234)
• Update golang.org/x/crypto to v0.37.0. This placates security scanners that were unable to see that pgx did not use the behavior affected by https://pkg.go.dev/vuln/GO-2025-3487.
• TraceLog now logs Acquire and Release at the debug level (dave sinclair)
• Add support for PGTZ environment variable
• Add support for PGOPTIONS environment variable
• Unpin memory used by Rows quicker
• Remove PlanScan memoization. This resolves a rare issue where scanning could be broken for one type by first scanning another. The problem was in the memoization system and benchmarking revealed that memoization was not providing any meaningful benefit.
