Обсуждение: [GENERAL] Renaming Raster Table
Hi All,
I used the raster2pgsql tool to load a raster with overviews into a PostGIS database using the following format:
raster2pgsql -s <SRID> -d -Y -e -I -C -F -M -l 2,4,8,16 /path/to/raster/file <table_name> | psql -h <host_address> -U postgres -p 5432 -d <database>
Now, I want to rename the raster table and I would like to know the affected tables and the required changes to be done without affecting the functionality of the raster/overviews.

While you may get a response here the PostGIS project appears to host its own mailing lists and you might find you get a faster/better response if you ask this very product specific question over there.

Hi Adrian,
Thanks for your response. I have already loaded the raster, but I want to rename the raster table and I am asking of how to do this without affecting the functionality of the raster/overviews.

The docs seem to cover this:
http://postgis.net/docs/manual-2.2/using_raster_dataman. html#RT_Raster_Loader
"-l OVERVIEW_FACTOR
Create overview of the raster. For more than one factor, separate with comma(,). Overview table name follows the pattern o_overview factor_table, where overview factor is a placeholder for numerical overview factor and table is replaced with the base table name. Created overview is stored in the database and is not affected by -R. Note that your generated sql file will contain both the main table and overview tables."
