In the following query (used by psql to show attribute defaults)
SELECT a.attname, pg_catalog.format_type(a.atttypid, a.atttypmod), (SELECT substring(pg_catalog.pg_get_expr(d.adbin,
d.adrelid)for 128) FROM pg_catalog.pg_attrdef d WHERE d.adrelid = a.attrelid AND d.adnum = a.attnum AND a.atthasdef),
a.attnotnull,a.attnum
FROM pg_catalog.pg_attribute a
WHERE a.attrelid = '32923' AND a.attnum > 0 AND NOT a.attisdropped
ORDER BY a.attnum
Is there some significance to the 128 other than simple formatting?
Also, if anyone knows when pg_attrdef.adsrc became unreliable, that would save
me some trouble. Thanks in advance.
