If the SELECT INTO clause attempts to load a value into a variable that is the wrong datatype, or not large enough to contain the value, an exception is raised. CrateDB has different types that can be specified if a table is created using the the CREATE TABLE statement. During the ensuing assignment to the local variable curtime, the PL/pgSQL interpreter casts this string to the timestamp type by calling the text_out and timestamp_in functions for the conversion. There is multiple ways how to get current timestamp in Python. Postgres allows us to define more than one function with the same name, so long as the arguments are not the same.
