I have been entering the data by having a command file that inserts the rows
one by one. (yes I know a copy command would probably be faster for
importing bulk data, but I prefer to insert each line individually)
IE: psql -U myusername mydatabase -f '/path/to/commandfile'
Inside the commandfile I have lines like:
INSERT INTO tablename (col1, col2, col3) VALUES ($val1, $val2, $val3);
How do I escape the data from a select statement? Something like: SELECT \*
FROM tablename; ?

What are you using to enter and retrieve the data?
Either escape the data before you put it in the database or when you retieve
it, whichever gives you the results you are looking for.
