comment ST_Union to merge tables containing lines?
Did you want a geometrical union? Seems like you want the union of tables: SELECT geom AS the_network_full FROM the_network UNION SELECT geom AS the_network_full FROM buildings_to_network_lines_table;

Before breaking,try v.clean with rmdangles (snap maybe could help too).

comment How to create polygons from a polyline graticule?
Mmm... those lines should be split. Have you try increasing the threshold in 'v.clean'?

comment How to create polygons from a polyline graticule?
That error means that it couldn't create any polygon. This used to be related with a noding problem. Try to use v.clean with the 'break' option in the Processing toolbox, then polygonize the new layer generated. It will add nodes on intersections and split all linework. Maybe could help.

comment how would one get the end points of a polyline?
Great answer, gene. Just one correction, the boundary of the MultiLineString could have more than 2 points if it is complex.

comment Make a polygon from intersecting lines in QGIS, using Polygonize or similar?
Are your lines noded on intersections? Crossing lines must be noded before executing the Polygonize algorithm. Not sure, but think 'Line dissolve' in the Processing toolbox could do that.

Hi calvillo! Are you sure is ED50? This could be ETRS89 too.

From Shapely (GEOS port) I don't know how to access Noder functionality too. The solution may be related.
