Joe Conway	96d1f423f9	Read until EOF vice stat-reported size in read_binary_file ... read_binary_file(), used by SQL functions pg_read_file() and friends, uses stat to determine file length to read, when not passed an explicit length as an argument. This is problematic, for example, if the file being read is a virtual file with a stat-reported length of zero. Arrange to read until EOF, or StringInfo data string lenth limit, is reached instead. Original complaint and patch by me, with significant review, corrections, advice, and code optimizations by Tom Lane. Backpatched to v11. Prior to that only paths relative to the data and log dirs were allowed for files, so no "zero length" files were reachable anyway.

Fujii Masao	d694e0bb79	Add pg_file_sync() to adminpack extension. ... This function allows us to fsync the specified file or directory. It's useful, for example, when we want to sync the file that pg_file_write() writes out or that COPY TO exports the data into, for durability.

Stephen Frost	11523e860f	Support new default roles with adminpack ... This provides a newer version of adminpack which works with the newly added default roles to support GRANT'ing to non-superusers access to read and write files, along with related functions (unlinking files, getting file length, renaming/removing files, scanning the log file directory) which are supported through adminpack. Note that new versions of the functions are required because an environment might have an updated version of the library but still have the old adminpack 1.0 catalog definitions (where EXECUTE is GRANT'd to PUBLIC for the functions). This patch also removes the long-deprecated alternative names for functions that adminpack used to include and which are now included in the backend, in adminpack v1.1. Applications using the deprecated names should be updated to use the backend functions instead. Existing installations which continue to use adminpack v1.0 should continue to function until/unless adminpack is upgraded.
