Re: bash or sql script to copy foreign table to locale table

Please do not hijack existing threads.

Hi all,

I need little help  please,

I'v  already   foreign tables (from oracle_fdw) in my  postgresql environment.

I'm Just  looking for  script shell  or sql  ( easy way)  to migrate  this  foreign tables   to locale  table .

My script below  has some issue

thanks lot

------script migrate---

#!/bin/bash
export PGDATA=/pg01/pgdata/9.6/data
export PGUSER="postgres"
export PGPORT="5433"
export PGPASSWORD="ttooe2"

for tbl in `psql -qAt   data_2020 -c "select  foreign_table_name  from information_schema.foreign_tables;"`;
do

                  ## note the added semicolon

    psql data_2020  -c "create table public.\"$tbl\" as select * from fdw_link.\"$tbl\";"

Here, either psql COPY the fdw_link.\"$tbl\" data OUT to a local file, and then COPY IN to public.\"$tbl\" OR INSERT INTO public.\"$tbl\" SELECT * FROM fdw_link.\"$tbl\";

done

----end  of script---

the database is :  data_2020

 foreign_table schema   is :  fdw_link

and want to copy  to public  schema
