Is there a way in Postgresql to call \ef or \df on a function or table name with wildcards. An example of the way I think it would work is \ef fn_%some%get%function%
This way I could find functions even if I only know part of the table or function name. Thanks for the help!
Yes you can use wildcards, this is explained in detail in the manual:
