POSTGRESQL BUG REPORT TEMPLATE

============================================================================

Your name :  Joshua Jackson
Your email address : jjackson@vortech.net


System Configuration
---------------------

Architecture (example: Intel Pentium) : Intel PIII
Operating System (example: Linux 2.0.26 ELF) : Red Hat 6.1 / Linux 2.2.14
PostgreSQL version (example: PostgreSQL-6.5.1): PostgreSQL 7.0RC1
Compiler used (example: gcc 2.8.0) : egcs-2.91.66

Please enter a FULL description of your problem:
------------------------------------------------

When using the "COPY" command to load a table in psql, if the row contains
an ASCII NULL (0x0) or the "\" character, it will ignore whatever the field
terminator for the column that this character is contained in.  The result
of which is all of the columns being shifted to the left (which results is a
failed insert of a given row).

Please describe a way to repeat the problem. Please try to provide a
concise reproducible example, if at all possible:
----------------------------------------------------------------------
A text file containing the following (each field seperated by tabs)

test1    test2    test3\    test4    1234    test5

to be copied into a table such as:

create table test(
    f1    varchar(10),
    f2    varchar(10),
    f3    varchar(10),
    f4    varchar(10),
    f5    integer,
    f6    varchar(10)
);

will fail with the error:
ERROR:    copy:    line 1, Bad integer input format 'test5'

The same result will be achieved if test3 was followed by an ASCII 0x0

If you know how this problem might be fixed, list the solution below:
---------------------------------------------------------------------
I assume that this has to due with C string termination and escape sequences
not being properly parsed.
