There is an option "-s oldname=newname", which changes the old field name of
the dbf-file to the newname in PostgeSQL. If the length of the new name is 0,
the field is skiped. If you want to skip the first field of the dbf-file,
you get the wildest error-messages from the backend.
dbf2pg load the dbf-file via "COPY tablename FROM STDIN". If you skip the
first field, it is an \t to much in STDIN.
A fix could be an counter j=0, which increments only, if a field is imported
(IF (strlen(fields[h].db_name)> 0) j++. And only if j > 1 (if an other field is
imported) the \t is printed.
An other small bug in the README:
-s start
Specify the first record-number in the xBase-file
we will insert.
should be
-e start
Specify the first record-number in the xBase-file
we will insert.

.SH DESCRIPTION
|
|
This manual page documents the program
|
|
.BR dbf2pg.
|
|
It takes an xBase-style .dbf-file, and inserts it into the specified
|
|
database and table.
|
|
.SS OPTIONS
|
|
.TP
|
|
.I "\-v"
|
|
Display some status-messages.
|
|
.TP
|
|
.I "-vv"
|
|
Also display progress.
|
|
.TP

Convert all field-names from the .dbf-file to lowercase.
|
|
.TP

.I "-u"
|
|
Convert the contents of all fields to uppercase.
|
|
.TP
|
|
.I "-l"

|
If this table already exists, first

.BR DROP
|
|
it.
|
|
.TP
|
|
.I "-D"
|
|
Delete the contents of the table specified with

|
|
.br
|
|
.br

|
.IR -f
|
|
operator has taken effect!
|
|
.TP

|
Specify the last record-number in the xBase-file we will insert.
|
|
.TP

program.
|
|
.br
|
|
Some charset convertions could cause the output to be larger than the input
|
|
and could break the program.
