Inconsistent SQL errors - Mailing list pgsql-general

I'm running PostgreSQL 8.4.3 on OS X Snow Leopard via MacPorts and I'm getting strange inconsistent errors such as:

dbuser-# select * from log_form;
ERROR:  syntax error at or near "select"
LINE 2: select * from log_form;
         ^

Then later the same query will run fine, as it should.
