pstrdup() will change source "system_time( stt , ett )" to "system_time( stt " and return "system_time( stt " when it is called in ValidateForeignTableOptions() and CStoreGetOptions(). But if I call it in somewhere else, it won't get wrong.
Here's my enviornment:
postgresql: psql (PostgreSQL) 12.10 (Ubuntu 12.10-0ubuntu0.20.04.1)
compiler: clang version 10.0.0-4ubuntu1
OS: WINDOWS sub linux GNU/Linux 5.10.102.1-microsoft-standard-WSL2 x86_64
How can I do to fix this problem?
