Abdul Yadi: PgDBF: convert FoxPro to PostgreSQL’s non-Public Schema

PgDBF: convert FoxPro to PostgreSQL’s non-Public Schema

Recently, I have to migrate Foxpro tables into PostgreSQL. I have downloaded the latest version of PgDBF originally written by Kirk Strauser (http://sourceforge.net/projects/pgdbf/files/latest/download?source=files), and successfully built the package. It run well. All foxpro data can only be stored in public schema, PgDBF does not offer option for other schema.

For that purpose I have created a patch. Once the package rebuilt, I can issue command with “upper-cased S” option -S myschema (assuming I have already had the schema in my PostgreSQL database):

pgdbf -S myschema myfox.dbf
