pg_lo_write — Write to a large object
pg_lo_writeconndescriptorbuflen
connThe handle of the connection.
descriptorA descriptor for the large object from pg_lo_open.
bufThe string to write to the large object (not a variable name, but the value itself).
lenThe maximum number of bytes to write. The number written will be the smaller of this value and the length of the string.
The number of bytes actually written is returned; this will ordinarily be the same as the number requested.
If an error occurs writing to the large object, a negative number will be returned. Other errors result in a Tcl error being thrown. Note that error handling for this command is different from most of the other Large Object commands.
