  1. [WIP] Patch : Change pg_ident.conf parsing to be the same as pg_hba.conf

    Amit Kapila <amit.kapila@huawei.com> — 2012-07-02T12:08:22Z

    Attached is a Patch to change the parsing of pg_ident.conf to make it
    similar to pg_hba.conf. 
    This is based on Todo Item: 
    http://archives.postgresql.org/pgsql-hackers/2011-06/msg02204.php 
    
    Purpose - This will allow to catch syntax errors in pg_ident at the startup
    or reload time.
      
      
    Changes are described as follows: 
    a.      Make the load_ident() functionality same as load_hba, such that it
    cleans the previous context, after successful parsing. 
    b.      Change the load_ident(), so that parsing can be done during load
    time and the parsed lines are saved. 
    c.      Change the functionality of parse_ident_usermap() so that parsing is
    not done during authentication. 
    d.      If load_ident() fails for parsing, it returns false and error is
    issued. 
            This point I am not sure, as for pg_hba failure it issues FATAL at
    startup. Currently I have kept error handling for load of pg_ident same as
    pg_hba  
      
    I have done the basic testing and test is still in progress. 
      
    Suggestions?

    Looks good to me, committed with some small cleanup.

    I think we should be more lenient with pg_ident.conf, and behave as if 
    the file was empty. That is the old behavior, and it seems sensible. You 
    can still connect using an authentication method that doesn't use 
    pg_ident.conf, but if pg_hba.conf is missing, you cannot log in at all.
    
    Thanks!
