Somebody was kind enough to write the answers down in the Wiki: http://wiki.postgresql.org/wiki/Matrices_Multidimensionales_con_funciones It is all in spanish, but the code examples should be helpful nonetheless. -- Alvaro Herrerahttp://www.CommandPrompt.com/ The PostgreSQL Company - Command Prompt, Inc. -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general

Do you actually need a 2-D array here? If so you'll have to initialize it to the right dimensions to start with, eg with a := '{{1,2,3,4,5,6,7,8,9,10},{1,2,3,4,5,6,7,8,9,10}}'; regards, tom lane -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
