How large would the database be?
Hard to said, since it depends a lot on the internal of the database
engine. Looking on the space used on disk for EPSG 7.09, I have 17 Mb
for Derby and 18 Mb for HSQL.
The EPSG database defines about 5000 referencing systems, but
applications will typically used only very few them, maybe 5. This is
0.1% of the database content (problem is that everyone may use a
different 0.1%). I think it would be unfortunate to load such a big
database in memory for using only 0.1% of it, which is why a tend to
prefer disk-based solution in the particular case of EPSG. Of course,
other kind of data would benefit more from memory-based solution.
