[dependabot]

Bumps github.com/jackc/pgx/v5 from 5.5.5 to 5.7.6.

Changelog

Sourced from github.com/jackc/pgx/v5's changelog.

5.7.6 (September 8, 2025)

• Use ParseConfigError in pgx.ParseConfig and pgxpool.ParseConfig (Yurasov Ilia)
• Add PrepareConn hook to pgxpool (Jonathan Hall)
• Reduce allocations in QueryContext (Dominique Lefevre)
• Add MarshalJSON and UnmarshalJSON for pgtype.Uint32 (Panos Koutsovasilis)
• Configure ping behavior on pgxpool with ShouldPing (Christian Kiely)
• zeronull int types implement Int64Valuer and Int64Scanner (Li Zeghong)
• Fix panic when receiving terminate connection message during CopyFrom (Michal Drausowski)
• Fix statement cache not being invalidated on error during batch (Muhammadali Nazarov)

5.7.5 (May 17, 2025)

• 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.

5.7.4 (March 24, 2025)

• Fix / revert change to scanning JSON null (Felix Röhrich)

5.7.3 (March 21, 2025)

• Expose EmptyAcquireWaitTime in pgxpool.Stat (vamshiaruru32)
• Improve SQL sanitizer performance (ninedraft)
• Fix Scan confusion with json(b), sql.Scanner, and automatic dereferencing (moukoublen, felix-roehrich)
• Fix Values() for xml type always returning nil instead of []byte
• Add ability to send Flush message in pipeline mode (zenkovev)
• Fix pgtype.Timestamp's JSON behavior to match PostgreSQL (pconstantinou)
• Better error messages when scanning structs (logicbomb)
• Fix handling of error on batch write (bonnefoa)
• Match libpq's connection fallback behavior more closely (felix-roehrich)
• Add MinIdleConns to pgxpool (djahandarie)

5.7.2 (December 21, 2024)

• Fix prepared statement already exists on batch prepare failure
• Add commit query to tx options (Lucas Hild)
• Fix pgtype.Timestamp json unmarshal (Shean de Montigny-Desautels)
• Add message body size limits in frontend and backend (zene)
• Add xid8 type
• Ensure planning encodes and scans cannot infinitely recurse
• Implement pgtype.UUID.String() (Konstantin Grachev)
• Switch from ExecParams to Exec in ValidateConnectTargetSessionAttrs functions (Alexander Rumyantsev)
• Update golang.org/x/crypto
• Fix json(b) columns prefer sql.Scanner interface like database/sql (Ludovico Russo)

Bug Report

Name	Severity	Example test case	Description
Potential vulnerability related to JSON null values	Medium	1. Create a table with a JSONB column. 2. Insert a row with a null value in the JSONB column. 3. Attempt to read the value back into a string variable.	The application might not correctly handle null values in JSONB columns, leading to runtime errors or unexpected behavior. This is based on the changelog for pgx versions 5.7.3 and 5.7.4, which mention fixes and a reversion related to scanning JSON null values. The code in core/src/plugins/postgres/postgres.go does not explicitly handle null values.

Looks like github.com/jackc/pgx/v5 is up-to-date now, so this is no longer needed.
