Subject: [pgjdbc/pgjdbc] PR #3633: fix: add validation for rectangular arrays in ArrayEncoding Closes #3567
Date: Sat, 17 May 2025 08:44:03 +0000
Message-ID: <[email protected]> (raw)

Add validation to reject jagged arrays during array creation.
Previously, jagged arrays caused silent corruption in text mode
or protocol errors in binary mode.

Validation includes:
- Recursive dimension checks for multi-dimensional arrays
- Null element preservation (PostgreSQL-compatible)
- Detailed error messages with array indices
- Full compatibility with valid rectangular arrays

Closes #3567
