Decoding UTF-T texts in PostgreSQL
This small extension program permits to decode the text tables of Infor baan IV or ERP LN. Those texts are encoded in UTF-T, so they need to be converted into UTF-8 for being used in a database.
While PostgreSQL is not currently supported by ERP LN, we connect it to baan or LN database using foreign data wrapper. This way we may develop applications on PostgreSQL.
In order to compile this extension, verify that you have pg_config in your path (it
should be part of the postgresql development tools).
Then, execute:
gcc -I$(pg_config --includedir) -fPIC -MMD -MP -MF pgutft.o.d -o pgutft.o pgutft.c
gcc -o libpgUTF-T.so pgutft.o -shared -fPIC
cp pgutft.o $(pg_config --pkglibdir)
once the library is installed in the postgresql extension directory, connect to your database as super user and execute
CREATE FUNCTION utft_to_utf8(bytea) RETURNS text
AS 'libpgUTF-T.so', 'utft_to_utf8'
LANGUAGE C STRICT;
If you want to let other users uses it, grant them the access to the function this way:
GRANT ALL ON FUNCTION utft_to_utf8(bytea) TO username;
if your text has many lines, join them as bitea, then pass it to utft_to_utf8() function:
select utft_to_utf8(text_from_baan_table);
