> This will not modify the parser, so postgress syntax such as:
> "... where c ILIKE '%ABC%'"
> will not be currently supported. It will simply be a function:
> "... where ILIKE(c, '%ABC%')"
> Same for substring:
> "select substr(c, 'abc')..."
> will be equivalent to postgress
> "select substr(c from 'abc')",
> but 'abc' will be treated as a java regex pattern.
