Description: =========== Error Message " invalid input syntax for type double precision: -1#I" is displayed while running "select pgstatindex"
Issue only getting reproduce on windows environment.
Analysis:
=========
Consider the following testcase to reproduce the issue on windows:
create table test (a int primary key );
Windows Output:
==============
psql>select pgstatindex('public.test_pkey');
ERROR: invalid input syntax for type double precision: "-1.#J"
Linux output:
==========
psql=# select pgstatindex('public.test_pkey');
pgstatindex
---------------------------
(2,0,0,0,0,0,0,0,NaN,NaN)
(1 row)
here when we run the select on linux its returning proper result and on
windows error coming from float8in() while trying to work for the NaN
values.
After debugging I noticed that "0/0" returning NaN on linux but it returns
"-1.#JIND0000" on windows. Now when float8in() getting call for such value
on windows it ending up with error "invalid input syntax for type double
precision:" as strtod() not able to understand such values.
I added to check into pgstatindex() to avoid "0/0" situation and issue got
fixed.
PFA patch for the same.
