Thanks. I made these noteworthy changes:

1. Fix lo_get(oid) on a LO larger than INT_MAX bytes: raise an error rather
than performing a modulo operation on the size.

2. Remove the undocumented ability to pass a negative length to request all
bytes up to the end of the LO. substr() also rejects negative lengths. Note
that one can get the same effect by passing any length >MaxAllocSize.

3. Documentation reshuffling. I placed all the documentation for these
functions in the large objects chapter, and I emphasized the new functions
over the prospect of calling the older functions (whose primary role is to
support client interfaces) from SQL.

If this still looks reasonable, I will commit it.
