- Added ::int type casting to LIMIT and OFFSET parameters for PostgreSQL
- Fixed parameter numbering: changed placeholder(len(args)+2) to placeholder(len(args)+1) for OFFSET clause
- Resolves error: pq: could not determine data type of parameter (42P18)
This fix ensures proper parameter binding when using PostgreSQL with the
whatsapp-bridge ListChats endpoint, which is used by the MCP server
to retrieve WhatsApp chat lists.
