Hi all
Sorry for the email, I am new at this list. I hope this is a correct way to
post issue.
Anyway what I have is:
1)
PostgreSQL 15.1 on x86_64-pc-linux-gnu, compiled by gcc (GCC) 4.8.5 20150623
(Red Hat 4.8.5-44), 64-bit
POSTGIS="3.3.2 4975da8" [EXTENSION] PGSQL="150" GEOS="3.11.1-CAPI-1.17.1"
PROJ="7.2.1" LIBXML="2.9.1" LIBJSON="0.11"
Query:
select ST_SRID(ST_GeomFromText('POLYGON ((4.9882543 50.4415584, 4.9882543
50.4415586, 4.9882545 50.4415586, 4.9882545 50.4415584, 4.9882543
50.4415584))',4326)), st_srid(ST_UNION(ARRAY[ST_GeomFromText('POLYGON
((4.9882543 50.4415584, 4.9882543 50.4415586, 4.9882545 50.4415586, 4.9882545
50.4415584, 4.9882543 50.4415584))',4326)]));
st_srid | st_srid

(1 row)
2)
PostgreSQL 17.0 on x86_64-pc-linux-gnu, compiled by gcc (GCC) 11.4.1 20231218
(Red Hat 11.4.1-3), 64-bit

Query:
select ST_SRID(ST_GeomFromText('POLYGON ((4.9882543 50.4415584, 4.9882543

50.4415584, 4.9882543 50.4415584))',4326)]));
st_srid | st_srid

4326 | 0
Is there a regression between those versions?
Thanks for any info and help
Best regards
