ECPG is single threading. Hence, tools written in ECPG are a pain in
the neck if you want multiple threads of execution. I recommend against
using it for any purpose except porting a single threading project that
already uses embedded SQL. The embedded SQL interface for PostgreSQL is
a disaster.
The libpq functions are reentrant. These will be useful for just about
any project.
If you are populating empty tables, then use the bulk copy interface.
It is orders of magnitude faster.
If you are going to completely replace the data in a table, drop the
table, create the table, and use the bulk copy interface.
