Dear PostgreSQL-experts,
may I request your advice for implementing the following application:
I have binary data vectors of experimental data, about 10 million of
them in total, each between 10 and 40 Kbytes long. I want to store the
experimental conditions pertaining to each of the data vectors in a
PostgreSQL database and the data themselves in a file. I want to do
this file-handling (creation, reading & writing) in a compiled (C)
language function, so that I can do everything over one database
connection, instead of having a separate program on a separate port
take care of the data files. Right now, I am converting the data
vectors to a string representation and back. But I wonder whether
there is a more efficient way of handing over the data to my function?
Thank you very much for your help.
Rolf
