Dear, I'm currently reading through the Postgresql documentation about how several functions work and which ones I would need. So far the documentation is great and well-structured! Unfortunally I'm not sure what functions will actually do when some non-obvious input is provided (which is sometimes required, as we cannot assume structure of the input at all times). A simple example is substring(text from 'blaat#"%#"' for '#') where text is not in the format of the regular expression, e.g. when text = 'text'. I don't know if the SQL standard includes such requirements, but documenting such behaviour might be a good addition to the help. If I know how and how to structure it, I'm willing to do some effect. In any case, something as already done for CREATE TABLE and such constructs are very good and well-defined.
