pglast VS zetasql

Can't you just give some love to the issue https://github.com/pganalyze/libpg_query/issues/44 instead ? As I said before this would be very helpful for the community because there are a lot of libraries that use libpg_query and cannot be used on windows (f.e see https://github.com/lelit/pglast/issues/7).

It seems that the only problem for fixing the problem is:

> Thanks for the offer, but the problem is our team being time limited / having an engineer with a Windows machine ready to take this on, not that we wouldn't want to pay someone to work on it :)

Hosting the LSP elsewhere is really needed since if people wanted to go that way they could use Remote ssh (https://code.visualstudio.com/docs/remote/ssh) to host the whole dev environment on linux and connect to it.

Thank you

Python: pglast

There are even table-valued functions.

These things are not widespread, and differ by implementation, and the way these are used by clients are copy-and-paste. Something as thoughtful as ZetaSQL https://github.com/google/zetasql does not have mechanisms for structuring (modules, packages, interfaces). SQL will not, cannot evolve into such a direction (or, anything that evolves, will not be recognizable as SQL).

Hi, I develop a BigQuery emulator ( https://github.com/goccy/bigquery-emulator ) from early 2022. It is written in Go, but can be used from bq command line tool and other language's (e.g. Python ) client SDK after installing docker image or released binary. It currently supports over 200 of the nearly 330 standard functions in BigQuery and all data types except GEOGRAPHY ( see https://github.com/goccy/go-zetasqlite#status for details ). ZetaSQL ( https://github.com/google/zetasql ) is used to parse and analyze queries.

We are using a Python client binding for ZetaSQL GRPC local service in our application to analyze statements and extract referenced tables and output columns.

If you don't want to do it yourself, there's this:

Parsing is huge but it's amazing how small a part of the job it is. This library isn't even the half of it.

I mean the postgres parser (and semantic changes) for ZetaSQL. The zetasql parser is in a file called zetasql/parser/bison_parser.y, I strongly suspect they now have a file called something like zetasql/pgparser/bison_parser.y as well (and much more pervasive changes to support the deeper differences in the dialects).

This is the lexical structure and syntax docs for the new postgres inteface to cloud spanner:

https://cloud.google.com/spanner/docs/postgresql/lexical

And this is the zetasql lexical structure and syntax docs:

https://github.com/google/zetasql/blob/master/docs/lexical.m...

Notice that the new PG docs are an edit of the Zeta ones - evidence that my hypothesis is correct.

zetasql implements BigQuery, Spanner, and Dataflow dialects.
