Thread: Is the max size of a table limited by the max file size of the file system?

Is the max size of a table limited by the max file size of the file system?

From

If I am right, for every table in a postgres database a file with a certain
number is created in the postgres data directory for the according database.

So my question is, if the maximum size of a table is limited by the maximum file
size of the underlying filesystem (e.g. 2GB for ufs). Or will a new file be
created if the limit is reached?

Thanks Andreas.

We segment tables in 1gig file chunks, so you are fine.

Good news, it's not.  As of about 7.2, postgresql started splitting all
it's datafiles at the 1 gig point.  so, you'll have files like this in
your base directory:

19283
19283.1
19283.2

as your table grows.  Sweet, huh? :-)
