If you are not constrained to psql you might want to have a look at my tool SQL Workbench/J
(http://www.sql-workbench.net/)which contains an export command to do just that: export all tables of a schema (or
multipleschemas) in a defined format, see here: http://www.sql-workbench.net/manual/command-export.html
Using that, this would be as easy as:
WbExport -outputDir=/some/export/directory
-type=text
-header=true
-delimiter=','
-sourceTable=public.*;
You also have more control over the format of the exported data than you would have with psql I dare say.
Disclosure: I am the author of that tool.
