I have dumps from oracle and microsoft sql server (no more details). Is it possible to load them "directly" into postgres (without oracle/mssql license)?
dump -> csv -> postgtres
or something ?
Asking the public mailing lists for PostgreSQL for an opinion on the the legality of doing something like this is problematic..
Technically it would depend a lot on exactly what you are trying to load. If you can go through CSV to do it then its probably just raw insert data and has a decent chance of working as long as the schema is PostgreSQL has been created to accept the incoming data.
