> Hello friends,

> I want to migrate a large Oracle table to PostgreSQL, which is
> approximately 200GB in size and includes a LOB segment. This table has a
> primary key column named "ID," which increments by one unit (similar to a
> sequence). During the migration of this large table, sometimes the process
> terminates prematurely (due to network issues, etc.). As a result, I have
> to restart the import process either from the beginning or by using a WHERE
> clause in the ora2pg configuration file to import the remaining data from
> where it was previously terminated.

> However, I've noticed that the import process in ora2pg doesn't seem to
> follow a consecutive order, starting from a small ID number and progressing
> to a larger ID number. Instead, it appears to import data randomly from
> various rows of the table. This makes it impossible to continue importing
> data from the point where it was terminated using a WHERE clause in ora2pg.

> My questions are:

> PostgreSQL table randomly and not sequentially from a smaller ID to a
> larger ID?
> - Or can we add additional parameters to the ora2pg.conf file to control
> this process and ensure that the data is imported sequentially, following
> the primary key from smallest to largest?
