Hi,
Approximate name matching was voluntarily restricted in 9.2.0 per
https://github.com/OSGeo/PROJ/commit/15a7cbeb124096b38e40f33202c5ba38f8e13a02
to avoid false positives in certain cases. I'm not sure why you get here
starting with 9.1.1 though
Trying with 9.1.0, I see
$ ~/proj/install-proj-9.1.0/bin/projinfo GK4
input string: parsing of user string failed: several objects matching
this name: Pulkovo 1995 / Gauss-Kruger CM 45E, Pulkovo 1942 /
Gauss-Kruger CM 45E, Pulkovo 1942 / 3-degree Gauss-Kruger CM 42E,
Pulkovo 1942 / 3-degree Gauss-Kruger CM 45E, Pulkovo 1942 / 3-degree
Gauss-Kruger CM 48E, ...
I'm not even sure to understand how that would match GK4...
Perhaps try with "Gauss-Kruger" or "Gauss-Kruger CM 4"
Even

Hi,
I try to convert data from the Gauss-Krueger-System using pyproj.
This worked well until pyproj 3.2.1 using code like prj =
pyproj.Proj("GK4"). Newer versions give me the error as mentioned in
the subject (pyproj 3.3.0) or even "unrecognized format / unknown
name" (pyproj 3.6.0). Since I get the error from the subject also when
using projinfo (9.1.1 on ubuntu 22.04) I decided to ask here whether
there are any means to get a fallback to the old behavior?
Thank you for providing this very useful library!
Best regards,
Michael
