dblink (at least the one distributed as contrib/dblink) is for
making connections to other PostgreSQL databases. You could,
however, use DBI-Link or something similar to make connections to
MySQL or another data source; in that case you could use the subquery
form of INSERT:
INSERT INTO tablename (columnlist) SELECT columnlist FROM ... ;
However, if you're just doing a one-time import of data from MySQL,
then it might be simplest to dump the data with separate INSERT
statements (mysqldump --extended-insert=FALSE).
