FWIW, I'm not excited about this. We accept "bool" and "boolean"
interchangeably, and it does not seem like an improvement for the
docs to use only one form. By that argument, somebody should go
through the docs and nuke every usage of "::" in favor of
SQL-standard CAST(...) notation, every usage of "float8"
in favor of DOUBLE PRECISION, every usage of "timestamptz" in
favor of the long form, etc etc.
