Hi Tom Lane,
In my case, we upload/download files to/from postgresql.
And we don't change the content of the file after once loaded to postgresql.
But as days going, more files stored to postgresql and never change file
content after that.
But download many times the stored files as per need.

MySQL supports procedures and functions.
Functions can return results but cannot update the database.
Procedures can update the database but cannot return results.
However :

Try doing the same test in MySQL (using InnoDB so you get a supposedly

Or even in Oracle.
