PostgreSQL version: 9.2.15
Operating system: Windows 7 Professional
Description:

1. My test Platform:

Windows 7 Professional Service Pack 1 32bit
Microsoft Windows [Version 6.1.7601]

2. test steps:

step1: download postgresql-9.2.15-1-windows-binaries.zip

step2: uncompress all sub-directories to "C:\Program Files\gaussdb"

step3: initdb
C:\Program Files\gaussdb\bin>initdb -D "d:\data"

step4: start server
C:\Program Files\gaussdb\bin>pg_ctl start -D d:\data

step5: Connect to the database to perform a simple query by constantly
calling psql.exe by a bat script.
the script is very easy, it's source code as followings:

@echo off
set n=0
:myAuto
"C:\Program Files\gaussdb\bin\psql.exe" -d postgres -c "select 1;"
echo %n%
set /a n+=1
if %n%==1000000000 (exit)
goto myAuto

When it is running for a period of time, an error will occur as followings:

Runtime Error!
Program:

R6016
- not enough space for thread data

3. I search some error about R6016, microsoft has some explain
https://msdn.microsoft.com/en-us/library/d509d9f9.aspx
and
https://support.microsoft.com/en-us/kb/126709#/en-us/kb/126709

but i still don't know the reason， is it a bug of psql.exe or some other
reason?

and win7 64bit platform can also occur the error besides win7 32bit
platform.
