Thank you very much,

I figured I needed to open my own using SPI_connect(). I had assumed that there was sth like a the-connection-this-functions-is-begin-run-through.

Now I'm having problems with

size_t inBufSize = 8192;
char* inBuffer = (char*)palloc(inBufSize);
int bytes_read = DatumGetInt32(DirectFunctionCall3(loread, Int32GetDatum(fd), CStringGetDatum(inBuffer), UInt32GetDatum(inBufSize)));


which returns an extremely large number in bytes_read (consistently 46235672), regardless of the contents of inBufSize.

I tried using lo_lseek(fd, 0, SEEK_END) on this fd already, which correctly returned the size of the Large Object, so it's not a question of an invalid descriptor. Also that seek didn't effect the result at all. I guess it's wrong usage of the DatumGet*() / *GetDatum() functions, but I can't see where.

Any suggestions?

What makes you think that "*the* current PGconn" is a valid concept? libpq has always supported multiple active connections.
