¿where is stored the value set by ALTER TABLE table_name ALTER COLUMN
column_name SET STATISTICS = [1-1000]?
I've set this to 1000, and I didn't remember in which column (doh!). Is
there any table to look? (I did 'grep "set stat" $PGDATA/pg_log/*' and found
it, but may be there is a better way)
I couldn't find it in the docs neithr "googling"
Greetings

pg_attribute.attstattarget
Example query:
SELECT attrelid::regclass, attname, attstattarget
FROM pg_attribute
WHERE attstattarget > 0;
See the "System Catalogs" chapter in the documentation for more
information.
