Hi,

I would like to load data from a file via file_fdw or COPY.. its a postgres 14 cluster

but.. One date (timestamp) column is written french order and another column is written english order. Data comes from a state owned entity so asking for a normalization may take ages.

obviously I could load as char and then apply an appropriate transformation. no pb.

But is there a direct way to do this ?

Probably no - casting formats via locale cannot be specified at that scope when using copy.  Either the cast for a given single setting produces the correct result or it doesn't.  If you need a custom cast like this you have to get away from COPY first.  Usually that is best done after importing data to a temporary table as text.

So, creating a foreign table with varchar type, and then doing the insert as select with the appropriate format.. clear.

somewhat sad as it was a one step process with the former oracle db we get rid off.
