You can write a function that takes a text/varchar and builds a dynamic SQL
query that then is executed...but I highly advise against it. Basically you
open yourself to SQL injection attack vectors and passing in a where clause
to a function is a very non-intuitive and cumbersome API.
What you likely want are functions that do what you want and take a person
id as an input. Let the user decide the best way to obtain that person id.
