DataException error for functions with default values

[charabaruk]

When expanding a connection to a Postgres database containing a function that has an argument with a default value, the operation fails and LINQPad shows the following message next to the database name:

(Error: DataException - Error parsing column 5 (ArgumentDefaults=System.UInt32[] - Object) (The field 'ArgumentDefaults' has a type currently unknown to Npgsql (OID 94). You can retrieve it as a string by marking it as unknown, please see the FAQ.))

Please catch the exception and work around any functions that cannot be properly resolved.

The signature of the function in question is

(IN id integer DEFAULT 0) RETURNS TABLE(id integer, iid uuid, parent_iid uuid, line text, body text, link_count integer, link_ids integer[], document json)
