Re: Display Bytea field

Alternatively, you could compare image checksums before and
after moving them into postgres. The advantage is that you
don't need to export or view any file, and you compare globally
all your images. If the checksums are identical, the data are identical.
On the MSSQL side, checksums can be computed with hashbytes()
as suggested in this stackoverflow answer: [3]
On the postgres side, use functions like md5() or sha256()
directly on the bytea column.
