Are you running GEOS > 3.9.
If so maybe ST_Union with a gridsize might work better for you needs over ST_Collect
https://postgis.net/docs/ST_Union.html
There are also a number of precision reduction functions
https://postgis.net/docs/ST_SimplifyPreserveTopology.html
https://postgis.net/docs/ST_SnapToGrid.html
come to mind

St_collect is used and size issue may cause the problem.
If just their relationship needs to be depicted, how can the size of geometry be reduced?
