Attached is a patch for REFRESH MATERIALIZED VIEW CONCURRENTLY for 9.4 CF1. The goal of this patch is to allow a refresh without interfering with concurrent reads, using transactional semantics.
I spent a few hours to review the patch.
Oh, BTW, though it is not part of this patch, but I came across this.
! /* ! * We're not using materialized views in the system catalogs. ! */ Assert(!IsSystemRelation(matviewRel));
Of course we don't have builtin matview on system catalog, but it is possible to create such one by allow_system_table_mods=true, so Assert doesn't look like good to me.
