Hello
why you don't use PQescapeBytea function ?

> I am trying to build SQL commands that insert values exported from a bytea column. Output facilities do not escape
singlequotes for bytea column. As such, the built INSERT SQL can be invalid because single quotes can appear in values.
Forexample, the built (invalid) INSERT SQL command can look like this:
>
> INSERT INTO t1 VALUES ('ABC\\000C'DE');
>
> Note the apostrophe between C and D.
>
> Are there straight approaches to do this job using version 8.x?
> Does the bytea hex export feature provided by version 9 help solve this problem?
>
> Thank you in advance!
