[postgis-users] Can I change the path of an out-of-db raster?

[guido lemoine]

Hmm, any thoughts on this? Just to expand my use case: I have a time series of images that are all spatially aligned, i.e. same size, geo-location, pixel spacing, projection.
Thus, raster2pgsql -R would always create the same tiled raster entries for each image where only the (binary) file name would be different. 
If one would simply be able to change the filename, a single set of tile records would be needed. That would be a neat concept for time series (other than creating massive multi-band images).

Something like ST_SetBandPath(rast, filepath) could be useful, although only in the aligned context.
