yaooqinn opened a new pull request #26573: [SPARK-29926][SQL] Fix weird 
interval string whose value end with a dangling decimal point
URL: https://github.com/apache/spark/pull/26573
 
 
   ### What changes were proposed in this pull request?
   <!--
   
   Currently, we support to parse '1. second' to 1s or even '. second' to 0s.
   
   ```sql
   -- !query 118
   select interval '1. seconds'
   -- !query 118 schema
   struct<1 seconds:interval>
   -- !query 118 output
   1 seconds
   
   
   -- !query 119
   select interval '. seconds'
   -- !query 119 schema
   struct<0 seconds:interval>
   -- !query 119 output
   0 seconds
   ```
   
   ```sql
   postgres=# select interval '1. second';
   ERROR:  invalid input syntax for type interval: "1. second"
   LINE 1: select interval '1. second';
   
   postgres=# select interval '. second';
   ERROR:  invalid input syntax for type interval: ". second"
   LINE 1: select interval '. second';
   ```
   We fix this by fixing the new interval parser's VALUE_FRACTIONAL_PART state
