you cannot copy postgres data files from one computer to second.
PostgreSQL is not MySQL. Use pg_dump instead or copy statement.

1. on PC1

pg_dump -t yourtable yourdatabase > yourtable.sql

2. copy yourtable.sql file from PC1 to PC2

3. on PC2

psql yourdatabase < yourtable.sql

your data file is not compatible with data dictionary.
