In this query result field 'numeric_precision' is set to 32 and
'numeric_precision_radix' is set to 2.
According to the documentation 'numeric_precision_radix' field should
indicate what radix the value of 'numeric_precision' is stored.
However, even though the radix is 2, the actual value is 32, which is
not a radix 2.
Could someone please shed some light?
What Postgres version?
Also the data_type is showing as integer not numeric so the numeric_*
values should be NULL.
What is the schema definition for the table?
When I run the query:
production=# select version();
version
-----------------------------------------------------------------------
PostgreSQL 9.6.2 on x86_64-pc-linux-gnu, compiled by gcc (SUSE Linux)
4.8.5, 64-bit
(1 row)
production=# \d projection
...
qty | numeric(7,2) | not null default 0
...
production=# \x
Expanded display is on.
production=# select * from information_schema.columns where table_name
='projection' and column_name='qty';
...
numeric_precision | 7
numeric_precision_radix | 10
numeric_scale | 2
....
Thank you.
