Full Changelog: v1.1.1...v1.2.0

Nightly build

Automated nightly build from main (7d863ad). These artifacts are unstable and intended for testing only.

v1.1.1

⚡ Highlights

🔒 SQL injection hardening in the replication path (identifier quoting, slot names, plugin options)
🔄 Materialized views refreshed after snapshot restore
🌳 Inherited / partition child rows excluded from CTID snapshots (ONLY)
🧩 Snapshot restore correctness: CLUSTER ON ordering, int4range/int8range typing, legacy handler functions

What's Changed

Security

• Improve SQL parameter binding and escaping by @kvch in #965
  • WAL identifier quoting now validates a single complete quoted token instead of trusting leading/trailing ", so a crafted source object name can't break out onto the target.
  • Replication slot CREATE/DROP bind the slot name as a parameter.
  • START_REPLICATION escapes table-filter plugin options and validates the slot name before use.

Bug fixes

• Refresh materialized views after data restore by @danddanddand (#908)
• Use ONLY for CTID snapshot queries to exclude inherited child rows by @danddanddand (#909)
• Restore CLUSTER ON statements after their referenced indexes by @danddanddand (#907)
• Type int4range/int8range values before INSERT/COPY by @danddanddand (#910)
• Skip legacy public PL/pgSQL handler functions on snapshot restore by @danddanddand (#906)

New Contributors

• @danddanddand made their first contribution in #906
