Hi,
How can I store Byte strings into a postgresql database.
Is there any special command to store it. How will be the sql query.
there is only '\0' byte incapable to input-output.
so u have to have it escaped at all costs _AND NOTHING MORE_.
"escaped" doesn't mean "prefixed with backslash"
("backslash method" cause a zero-byte to pass SQL parser an to be actually stored, BUT
the output will be corrupted, because of this zero-byte will be actually output)
You may use the BYTEA type
(similar to the TEXT but with different input-output) which effectively escapes zero-byte and a lot of other completely harmless bytes as well (probably to reach a better overhead)
Or you may introduce a pair of your own escape rules.
Unfortunately there are no way to influence The Pg Developers to get rid of the nasty god damned CSTRING off the input/output operations.
