I face this same problem when I try to insert image by lo_import to
database with my client files. I already change the way to bytea data
type but it's not work. The error return like type mismatch when I try
to insert it from Binary variable.
Why I cannot insert it? If anybody found some solution please reply on
this topic for me too.
Thank You.

have you succeeded in inserting an image into the database from a file
on the
server using the above query? AFAIK you need a bytea datatype, and also
the
image data has to be properly escaped (\\) before pg will accept it. I
assume
you are using a scripting language with a dbapi. Your steps would be:
1. read the image file into a variable
2. escape the image data
3. insert this into the database in a bytea field
if you follow this procedure it is irrelevant as to where the source
file is
- client or server
