Hi David,

I mean the ones with "::" like ::text or ::uuid etc

Some of Postgresql data types have two words or more like "double precision"
or  " timestamp without time zone". It is not clear how these are
implemented if at all.

Many thank.

Do you mean implicit casts - those that do not require an explicit CAST(...)
or "::" in the query?

Can you give an example of one that you know exists?

The catalog is probably the best way to get a definitive list though I do
not know the exact query you would use.  The catalog tables are fairly well
documented so you should start there.
