Error: DB error: insufficient permissions

Hi Last week managed to set up Nominatim successfully following the instructions provided by OSM. However there was one problem where the gb_postcode database was not created. I think it was because it was using deprecated functions so I have replaced them with the newer alternatives.

I have my postgres user set up as the same user of the computer just as the instructions mention.

I run the following command: ./Nominatim-2.0.0/utils/setup.php --osm-file osmfile.osm.pbf --all

But I get a permissions error as follows:

ERROR: DB Error: insufficient permissions
DB Error: insufficient permissions

I have ran the chmod +x command on all the directories mentioned in the instructions.

I don't understand why this error occurs. I managed to run the command last week but I can't think of what has changed.

Can anyone help?

Thanks
