The epsg file is missing because the bundle uses proj-6.0.0 which no longer has an epsg file.
GRASS 7.6 is not compatible with proj-6+, please rebuild with proj-5.x.
Thanks and my apologies -- I suspected something like that but was unable to figure it out.
(I did something really wrong which appears to work, however: copied epsg from another GRASS 7.4.1 precompiled bundle installation from the same source I had on the same machine.)
I now see it in release notes for proj-6.0.0 that all CRS stuff in the proj.db SQLite3 database file: https://proj.org/news.html#id41
I wonder why the bundle was built with an incompatible proj-6 libary -- it that going to break a lot of GRASS functionality other than the missing epsg file?
Should I close the bug as it is apparently not a bug?

Yes, reprojections are affected because the bahviour of proj changed: previously, it expected coordinates in the order east, north. Now it depends on the CRS definition, e.g. commonly used EPSG:4326 defines an order of north, east. Previously it expected coordinates for ll to be in radians, now it also depends on the CRS definition (commonly degrees, not radians for ll). That means even if you patch in the old epsg file, coordinate transformations might be wrong. Not to mention the new temporal dimension and the new availability of more accurate transformation pipelines.

Maybe we should add a configure check for proj-6+ to GRASS 7.6.
