Hi , i want to develop an index for a special problem. The postgres docs shows the necessary bits in http://www.postgresql.org/docs/8.4/interactive/indexam.html especially paragraph 50.2 "Index Access Method Functions". Now my question: can i use the (documented) Server Programming interface within this functions (e.g. SPI_exec within ambuild) or do i need to use other (possibly undocumented) functions. Background: The index needs some metadata which can be created within "normal" tables. Otherwise this information must be built within the index. And as an appendix to my question: Are there any (simple) examples for custom indexes ? greetings uwe -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
