Hello, I am doing some research on postgres sql query parsing.
I have found the https://github.com/lfittl/libpg_query project which manages to re-use the native postgres server parser. For using this, you need to accept an external dependency on a lib compiled out of the postgres source. I was wondering what people think of the conformance with regards to the real parser of the documentations on - https://www.postgresql.org/docs/current/static/sql-select.html - https://www.postgresql.org/docs/current/static/sql-copy.html ... and more generally sgmls in https://github.com/postgres/postgres/tree/master/doc/src/sgml/ref Would it make sense to use these sgml synopsis as some kind of source of truth, parse them, and automatically generate a parser for a specifc language ? This could enable the creation of parsers for different languages using parser generators based on the synopsis. I feel like the conformance level of the documentation is high and that the sgml synopis seem to be nearly programmatically sufficient to create parsers. what do you think ? Could the parser commiters share some lights on how the documentation process interacts with the parser commits ? Thanks, Jerome
