So is SqlDB+PostgreSQL not tested or Alpha / Beta quality? I was hoping to use it in a production environment. PostgreSQL seems to be a lot more powerful than other open source database + the PostgreSQL tools like pgAdmin III are brilliant. > This probably didn't exist when this code was written (postgres 5) and > the information_schema is probably just a view which references to > pg_attribute... Yes, any implementation of "information_schema" is normally a view. The nice thing is that even if the underlying system tables change, the information_schema views will not. Hence the reason it is preferable to use the information_schema's if they exist, instead of querying the system tables directly. Is it still worth supporting anything before PostgreSQL 7.2 - as far as I can see many major changes (for the better) occurred after 7.2 and 8.0. Hey, the database server is free, so there shouldn't be any reason not to upgrade. :-) > Could be. In fact, Bytea is not a blob field. So to support blob-fields, All the documentation I read suggests that Bytea is used for BLOB types. And Firebird's "blob subtype 1" is equal to "Text" in PostgreSQL. > the databases you are used to use.

As far as I understood the documentation, that is all handled internally by PostgreSQL. Users do not need to worry about something like that, you use Bytea just like any other field type. The server stores BLOB (bytea) data in a separate location to overcome the table row size limit. Internally a reference is used in the users table, but the end user never sees that. > But please create bug-reports, preferrably with actual user-case > problems, not only based on the code, but also show the results.

I'm determined to get Free Pascal to pass the extensive test suite of tiOPF. The database test suite gives the DB components a very good workout. SqlDB+Firebird is doing pretty well, but SqlDB+PostgreSQL still fails a lot of tests. Both are not 100% pass rate, but hopefully when I am done, they will be.
