create table my_stuff (data bytea);
I then try to insert 10 1M blobs into this table using PQexecParams from C. It takes ~10 seconds to insert the 10 records.
The test is being performed locally so this is not a network issue. If I change the data I send from the client to 1M worth of text, and change the 'my_stuff.data' to TEXT, the same test takes ~2 seconds. Has anyone else seen this performance issue with bytea?
I looked at large objects but that is limited to an Oid and I will need more than 4 billion unique identifiers. Maybe not 4 billion objects at once, but I will burn through them quickly.
I looked at the byteain and byteaout functions in the postgresql source and there is quite a bit of processing going on - escape stuff. Although, this is for text-to-internal correct? If I use PGexecParams setting the format to binary, the backend should use the recv/send functions ... right?
I don't need this escaping; this information never needs to be in text form. Is it possible to create a user-defined type that's only binary? It looks like I am forced to defined an input and output function. The input function takes a CString.
Any other solutions for getting binary data into postgresql? Suggestions?
