Description

The .pegjs files total ~1.45MB and are all loaded upfront. I would guess that most users (like myself) only use one SQL dialect in their project, so loading only that specific parser would significantly reduce their browser's download time (nm, I see that's what the separate <dialect>.umd.js files are for) or their Node.js process' startup time.

Research direction

Start by tracing how the .pegjs files are loaded during Node.js startup, then compare that path with the separate .umd.js files mentioned in the issue. Done means parser loading is conditional rather than loading all dialects upfront, with startup behavior checked for the affected usage.
