Comment(by dustymugs):

 For changing the alignment of a raster:

 {{{
 1. ST_Realign(
         rast raster,
         upperleftx double precision,
         upperlefty double precision,
         skewx double precision DEFAULT NULL,
         skewy double precision DEFAULT NULL,
         algorithm text DEFAULT 'NearestNeighbour',
         maxerr double precision DEFAULT 0.125
 ) -> raster
 }}}

   upperleftx: the X component of the corner of the upper-left pixel of the
 resampled raster. default is NULL indicating that the user isn't
 realigning the raster

   upperlefty: the Y component of the corner of the upper-left pixel of the
 resampled raster. default is NULL indicating that the user isn't
 realigning the raster

   skewx: the X component of the resampled raster's skew. default is NULL
 indicating that the skew of the original raster will be applied to the the
 resampled raster

   skewy: the Y component of the resampled raster's skew. default is NULL
 indicating that the skew of the original raster will be applied to the the
 resampled raster

 {{{
 2. ST_Realign(
         rast raster,
         upperleftx double precision,
         upperlefty double precision,
         algorithm text,
         maxerr double precision DEFAULT 0.125
 ) -> raster
 }}}
