It hung during last night's run.
I had modified my batch script to run the \copy commands separately, i.e. it now reads as : psql -h myserver -a mydb < originalscriptwithoutproblematicline.sql psql -h myserver -a mydb < problematicline.sql
It hung at the problematic line, so during the second psql command.
I'm really at loss... I *believe* that the problem lies either in psql or in PostgreSQL, but I really don't know what to try now.
