Hi,
There was a project done over the parser over Postgresql 9.1.1
I am trying currently to migrate it to Postgresql 10.4. Even if I did everything In the parser itself I started receiving errors from preproc.y which I observed is not presented in Postgresql 9.1.1 and I am struggling a bit. I tried to find some README or documentation related not to start from scratch checking the details but unsuccessfully.
Can you share any information/links/articles, please? Also, relationships between the parser y file and the preproc.y?
Thank you in advance!
Kate
