Re: How to import/export data from/to an ASCII file?

Try \copy or copy commands in psql:

I normally use \copy for tab-delimited files.
But copy also works and has help....

\h copy
Command: COPY
Description: Copies data between files and tables
Syntax:
COPY [ BINARY ] table [ WITH OIDS ]
FROM { 'filename' | stdin }
[ [USING] DELIMITERS 'delimiter' ]
[ WITH NULL AS 'null string' ]
COPY [ BINARY ] table [ WITH OIDS ]
TO { 'filename' | stdout }
[ [USING] DELIMITERS 'delimiter' ]
[ WITH NULL AS 'null string' ]
