[GRASS-user] g.gui.psmap issue

[Rich Shepard]

   Using 7.7.svn (r73654) g.gui.psmap will neither display nor save a .ps
file when a vector map display is constrained to certain attribute table
rows and the select where <column_name> is set to a string.

   This is the script:
# timestamp: 2018-11-09 09:32
# location: willamette_basin
# mapset: mercury
# page orientation: Portrait
# g.region vector=wrb at mercury

     end

end

   Is there a work-around for this?

TIA,
