[ADMIN] ERROR PARSER: parse error at or before 'constraint'

[joe briggs]

Hello,

When I try to import a data base from one Linux box to another ( cat
db.out | psql dbname ), I get an error:

ERROR PARSER: parser error at or before 'constraint'.

The source box was Linxu 6.1 with PostgreSQL 7.0 manually installed.
The target box has been the same configuration, but also a RH61 with
default PostgreSQL installation.  Results are the same.

I would appreciate ANY suggestions.
