Is there a way to use a variable as the name of a table or column in plpgsql? This might be a simple question, but I can't find the answer in the docs. http://www.postgresql.org/docs/8.2/interactive/plpgsql-declarations.html hints that there are data types that correspond to table/column, but I don't see them listed here http://www.postgresql.org/docs/8.2/interactive/datatype.html ... Also, I assume that once I figure out the right datatypes, I can assign to them from functions like substring()? Thanks, Gary
