[Moose-dev] Re: Anyone can explain this PParser behaviour?

Op 26 feb. 2016 om 22:54 heeft Anne Etien <anne.etien(a)univ-lille1.fr&gt; het volgende geschreven: We briefly have a look with Nicolas today and it seems that there is not the description of the function with begin, end. But it is not so strange when we have a look at postgresql 9.5 specifications http://www.postgresql.org/docs/current/static/sql-createfunction.html (definition: A string constant defining the function; the meaning depends on the language. It can be an internal function name, the path to an object file, an SQL command, or text in a procedural language.) Hard to parse in that condition and we want to parse the content of the function. Any idea? Is there a pl/psql grammar?
