if the python-variable strings contain just printable characters (ASCII 32 -
126) you should only need to escape out the single quote (') and blackslash
(\) characters for postgresql.
replace ' with '' and \ with \\. i don't know about Python but Perl DBI has
a function called quote() used to correctly quote and escape SQL statements. my $quotedString = $dbh->quote( $string
);
if the python-variable strings contain other special characters you can
escape those characters to slash followed by their 3 digit ASCII octal value
(decimal 10 = \n = \012).
INSERT INTO foo (varname) VALUES ('var''s name\\!@#$%^&*()_\n\012');
