pg_dumpall's charter is to be able to recreate a database cluster's contents in a virgin installation, but it was failing to honor that contract if the cluster had any ALTER DATABASE SET default_transaction_read_only settings. By including a SET command for the connection for each connection opened by pg_dumpall output, errors are avoided and the source cluster is successfully recreated. There was discussion of whether to also set this for the connection applying pg_dump output, but it was felt that it was both less appropriate in that context, and far easier to work around. Backpatch to all supported branches.
