-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi list, I've asked this question already on the PostGIS list, but I think it might get great answers here too. I'm running two database cluster with PostGIS 1.5 and PostgreSQL 9.1 on FreeBSD 9.2-RELEASE-p3 and apparently my PostGIS and PostgreSQL are a little bit outdated. Now the plan is to upgrade both PostGIS to 2.1 and PostgreSQL to 9.3, which are the latest versions in the ports. Now, I am a little bit lost with all the precautions and measures one has to undertake to do the hard upgrade. From what I read on the PostgreSQL site, I can choose whether I want to use pg_upgrade (without the need of a intermediate dump) or pg_dumpall to put the data aside. I presume I can't use pg_upgrade since this wouldn't take PostGIS into account, right? That leaves me with pg_dumpall for the PostgreSQL upgrade. Now, reading the PostGIS instructions to upgrade I come to the conclusion that a binary dump is required to put the data aside while doing the upgrade. Thing is pg_dump only dumps one spatial database, and I have several in my clusters, so I'd need to dump all of them, right? And here's where my confusion starts, since there are different tools used for PostgreSQL and PostGIS for the individual upgrade. What would be the correct procedure to dump a complete cluster in a PostGIS and PostgreSQL compliant way? My ideas so far: Step one: Use pg_dumpall to dump the roles and cluster metadata Step two: Iterate and use pg_dump in binary mode to dump every database in the cluster Step three: rename/empty the target drive/folder Step four: do the upgrade of PostgreSQL and PostGIS Step five: restore the roles and metadata Step six: use the command utils/postgis_restore.pl to restore each individual database Does that look sound? On a side note, I tried upgrading each part individually, but the port dependencies won't let me do that because upgrading PostgreSQL to 9.3 will also pull PostGIS 2.1 and upgrading PostGIS 2.1 will also pull PostgreSQL 9.3, so I only get the two of them ... Any tips on the procedure are greatly welcome :-) Frank - -- Frank BRONIEWSKI METRICO s.à r.l. géomètres technologies d'information géographique rue des Romains 36 L-5433 NIEDERDONVEN tél.: +352 26 74 94 - 28 fax.: +352 26 74 94 99 http://www.metrico.lu -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQEcBAEBAgAGBQJS80FVAAoJEHopqW0d1cQVjzMIAJQ6povfOSYg0NIw5DXF0KlZ 0MQQjwoOwRIPrCkllwDEpmioI2OtkBH03LYuQQYi8SArovtBRlTwyvZsUgFuuxy6 qAQhHcGxLyJPvxBIXVRhqnmn89a1otGxXTI+ZedNbJsj74vW0h29KRBAyklphe/C iAGw8+2zr0yiBLJdHWZvnMdS0PkL4jc7UY1XfmCg3AvNQU1EgiUYdWOEn26fqj0g bXrpHERgv8c+Hk8r8/G4WRD6rC0aMirB0lynxn+FHhSc9mzXUbDbER99M06vXrtF uIIeOTfr/Pu5eyjHDc3stg2LAtoNTvnvvJ0S+5Shi6ndLRy3P7AHZ6y915AMkRA= =4KIY -----END PGP SIGNATURE----- -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
