You need to escape the data before you insert it.  This is language-
dependant, but any language that has PostgreSQL libraries will have
functions to escape text data.

Also, given that his main problem seems to be with backslashes, using
8.2 and setting standard_conforming_strings = on might help.  It's still
the case that not using a proper escaping function will come back to
haunt you someday, though.

Has anybody written a 'proper escaping function' in php, something along the lines of addslashes()?
