Instead of implementing a pool of connections that the system implicitly
manages, it might be better to implement named connections as it is done
in Postgres
(https://www.postgresql.org/docs/current/static/contrib-dblink-function.html)?
Which the user manages and re-uses as he needs - he knows

I don't see how persistent connections in Postgres could be reused by
different user sessions.
No, in Postgres you can reuse only your own connections.
Nevertheless, it seems to me that this approach also solves the original
task
Hello.
The background of this task in CORE-5612, it contains research details
and conclusions.
How much I understood, there is no way to specify what index should be
used at system inquiries from *.epp files?
If not, is it possible to enable the create/delete, enable/disable
indexes on
sertString(isc_dpb_gbak_attach, FB_VERSION, fb_strlen(FB_VERSION))),
but then you need to remove the check for the creator of database
(attachment->att_flags & ATT_creator).

I was not entirely right.
The above tests were carried out on version 2.5.5, where the result was
obtained in 30 minutes.
After upgrading to version 2.5.8, the test shows the same results
regardless of the processor ~ 1 min.
Also checked for version 3.0, with additional indexes created in
The implemented feature allows changing user indexes to any users.
Perhaps it makes sense to allow this only for users who are members of
the RDB$ADMIN role?
Or is it better to check by analogy with database triggers -
SCL_check_database(tdbb, SCL_alter)?

I have the same understanding
It seems to me that the solution of this problem would be of much more
use. Then you could just create additional system indexes and use those

restored from 2.5 backup and can't be removed afterwards. I suggest to
