Tom Lane 0bb51aa967 Improve parsetree representation of special functions such as CURRENT_DATE. ... We implement a dozen or so parameterless functions that the SQL standard defines special syntax for. Up to now, that was done by converting them into more or less ad-hoc constructs such as "'now'::text::date". That's messy for multiple reasons: it exposes what should be implementation details to users, and performance is worse than it needs to be in several cases. To improve matters, invent a new expression node type SQLValueFunction that can represent any of these parameterless functions. Bump catversion because this changes stored parsetrees for rules.
