Contrib module implements toaster for non-compressed bytea columns, which allows fast appending to existing bytea value. Appended tail stored directly in toaster pointer, if there is enough place to do it.
Note: patch modifies byteacat() to support contrib toaster. Added varlena changes for bytea_appendable_toaster and added bytea toaster to makefile 0005_bytea_appendable_toaster patch
