As Udf’s are depricated, are somwhere all current udfs rewriten in udr form?
I mean about fbudf.dll and ib_udf.dll and with source code to look at it
as a sample for self written „udr_udf” ?
Yes they are, for Firebird 4.

No, it isn't. From the beginning it is a kind of plugins with fixed
interface.

Blob filters are a special type of UDF, and in Firebird 4, UDF will be
deprecated. Are there any plans for replacement, for example, defining
blob filters through UDR?
For me this is primarily academic curiosity, I don't actually use blob
filters myself.

Yes it does, this would introduce a semantic ambiguity (and probably a
syntactic ambiguity. In the original syntax
n-standard clause **at the end** of the CREATE TABLE statement. Maybe
something like the PostgreSQL WITH-clause (although using that specific

Going over the Firebird 4 release notes, I was wondering if there is a
isc_database_info / Attachment::getInfo() call to determine if a
database is standalone (no replication), a primary, or a replica
status, I would also be OK with considering standalone
databases a primary.
I didn't see anything for this listed in "Extensions to various
getInfo() Methods" of chapter 4.
