- src/tools/rebuild_hooks.ts:31-61 (handler)The execute function implementing the rebuild_hooks tool, which restarts the pg_net worker using net.worker_restart() SQL.

' (Is pg_net installed and enabled?)' : ''}`; console.error(message); return { success: false, message }; } // If no error, assume success console.error('pg_net worker restart requested successfully.'); return { success: true, message: 'pg_net worker restart requested successfully.' }; } catch (error: unknown) { // Catch exceptions during the RPC call itself const errorMessage = error instanceof Error ? error.message : String(error); console.error(`Exception attempting to restart pg_net worker: ${errorMessage}`); return { success: false, message: `Exception attempting to restart pg_net worker: ${errorMessage}` }; } }, - src/tools/rebuild_hooks.ts:8-22 (schema)Zod input/output schemas and static MCP input schema for the rebuild_hooks tool.
