trouble with getting the field names

[John-681]

Below is a SQL statement that was created to retreive the primary key , and
column names and data types for a table name and a schema.  The problem is
that is works very well if I only use the 'public' schema.  But it does not
work if I use a 'system' schema I created (owned my me).  The offending line
is "AND pg_table_is_visible(c.oid)"  which makes me believe I done something
wrong with the roles?  IOW if I drop the "pg_table_is_visible" it works with
my 'system' schema.  So I need a better guru than myself to help/tell me what
I did wrong.  Thanks in advance!

SELECT a.attname, t.typname,
EXISTS(SELECT * FROM generate_series(0, 31) idx(n)
WHERE a.attnum = i.indkey[idx.n]) AS isprimary
FROM pg_class c
JOIN pg_namespace n ON n.oid = c.relnamespace
JOIN pg_attribute a ON a.attrelid = c.oid
JOIN pg_type t ON t.oid  = a.atttypid LEFT
JOIN pg_index i ON i.indrelid = c.oid AND i.indisprimary
WHERE c.relname = 'sys_company' AND n.nspname = 'system'
AND a.attname NOT IN  ('ctid', 'cmin', 'cmax', 'tableoid', 'xmax', 'xmin')
AND has_schema_privilege(n.oid, 'usage')
AND has_table_privilege(c.oid, 'select')
AND pg_table_is_visible(c.oid) ORDER BY c.relname, a.attname

OK I discovered the problem I needed to add
… ALTER USER test SET search_path TO schema1,schema2

thanks
