Hi, pgsql-committers!
I cannot created more than 32766 databases with freeBSD in one setup,
not as the document says, "as many as you like".
I found the problem is that the directory pgsql/data/base cannot hold
more than 32766 subdirectories.
I suggest to make 32766 subdirectories in base directory, say /base/0,
/base/1, .... /base/32765. Then in each subdirectory to put the
database description.
This way, we can have 32766x32766 databases. This is kind of "as many
as you like".
The ZFS system is not a solution for me. It is snail slow.
