1.ERROR: line 1, "Bad date external representation" when executing copy
cliente from '/home/txtfiles/cliente.asc' with delimiter as '|'.

2. ERROR: copy: line 1, "Extra data after last expected column" when
executing copy maxtrn from '/home/txtfiles/maxtrn.asc' with delimiter as

a. The text file "maxtrn.asc" was generated by Informix Online 5.0, and
its  structure is:
5|02|C|286|
5|40|C|287|
b. The table "maxtrn" has columns:
cvesuc int2
cuenta char(2)
cvetrn char(1)
folio int4

3. I cannot connect to PostgreSQL database from Kylix 3. I got the error
message "DbExpress Error: Invalid username/password"

a. I'm trying to connect with the account "postgres" which was generated
by RH Linux 9.0 and I verified entrance to the account with the password I
assigned to it previously.

Thanks for your help!!

Can't help you on that without seeing the data it's objecting to.

COPY thinks that these data lines have five columns, with the fifth being
empty.  You can either get rid of the trailing "|" characters (a quick
sed script would do it), or you can make COPY happy by providing a fifth
column to import into.  For instance,

        ALTER TABLE maxtrn ADD COLUMN junk text;
        ... COPY ...
        ALTER TABLE maxtrn DROP COLUMN junk;

Sorry, dunno anything about Kylix.  If you can show us the message that
shows up in the postmaster's log (postmaster stderr output) when you try
to connect, maybe we could help.

Please show us the date value on line 1.

Yes, this is a known problem.  Informix puts the delimiter at the end of
the line, while we don't.  You have to strip them, perhap with sed:

    sed 's/|$//' file

Not sure on that one.  Perhaps it is using an older PostgreSQL client
library and you have to use 'password' or 'crypt' rather than 'md5'.
