Hmm. Here
src/backend/access/transam/xlog.c read_tablespace_map()
using %s in scanf looks suspisious. I don't fully understand but it
looks like it tries to read oid as string. So, it should be safe in
usial case

Next, _LoadBlobs() reads filename (fname) with a help of sscanf. Could
file name be in UTF-8 encoding here?

This function reads the "blobs.toc" file. It lines have the following format:
<uid> <filename>

Where <filename> is blob_<uid>.dat.

Therefore it should be safe too.
