[GRASS-user] postgreSQL import

GRASS GRASS user
1

I try to import various files from PostgreSQL to GRASS in GRASS70.

db.connect driver=pg database=‘host=,dbname=,schema=’
db.login user=“sustaincity” pass=“+++”
db.connect -p
db.tables -p |less

for i in {1…3};
do
v.in.ogr dsn=‘PG:host= dbname= user=’ layer=schema.layer output=layer$i type=boundary,centroid -o --o;
done

This does only work for few layers. Some layers have many items inside and these are not recognized, although I can view them through db.tables -p.:
ERROR: Layer <schema.layername> not available

any ideas?
