hello group,
I just started to use postgresql and i want to import data using copy command
in
a loop.
Here is what i did !
1) following content with name loaddata.sql.
\copy table from 'C:\psql\x.txt';
\copy table from 'C:\psql\y.txt';
2) My loaddata.sql is located in C:\psql\ therefore i
\i C:\psql\loaddata.sql
But it says C:: Permission denied
Give the permission to postgres user on 'loaddata.sql' file. Right click and
in properties give full access to postgres user.

I figure you have a reason for considering using nulls but since you didn't
explain the underlying problem you are trying to solve it is hard to comment or
consider. If you share there may someone who can provide a solution that
doesn't violate best practices and common sense.

It probably is, the default Postgres settings are quite modest and GIN
indexes are memory hungry.
I think you need to increase shared_buffers. With 2.5GB of memory (such a
strange number) the docs suggest about 250MB.
