Changelog

  • Fixed the issue with pg_tde running out of memory used for decrypted tuples. The fix introduces the new component TDEBufferHeapTupleTableSlot that keeps track of the allocated memory for decrypted tuples and frees this memory when the tuple slot is no longer needed.

  • Fixed the issue with adjusting a current position in a file by using raw file descriptor for the lseek function. (Thanks to user rainhard for providing the fix)

  • Enhanced the init script to consider a custom superuser for the POSTGRES_USER parameter when pg_tde is running via Docker (Thanks to Alejandro Paredero for reporting the issue)
