      Description

      Unable to connect to psql for current database.
      We can access psql for template1 database but for current database we are getting the following error:

      #psql 
      psql: FATAL: could not count blocks of relation 1663/16508/1249: Not a directory
      

      When trying to failover to Standby and starting HAWQ Master we get the following error again:

      On both Master and Standby, we can see that pg_attribute for current database, file 1663/16508/1249 has reached 1GB in size:

      [gpadmin@master]$pwd
      /data/hawq/master
      [gpadmin@master master]$ cd  base
      [gpadmin@master base]$ ls
      1  16386  16387  16508
      [gpadmin@master base]$ cd 16508
      [gpadmin@master 16508]$ ls -thrl 1249
      -rw------- 1 gpadmin gpadmin 1.0G Feb 16 18:24 1249
      

      From strace we were able to find the following:

      [gpadmin@master master]$ strace  /usr/local/hawq/bin/postgres --single -P -O -p 5432 -D $MASTER_DATA_DIRECTORY -c gp_session_role=utility currentdatabase <<EOF
      select version();
      EOF
      
      (...)
      
      open("base/16508/pg_internal.init", O_RDONLY) = -1 ENOENT (No such file or directory)
      open("base/16508/1259", O_RDWR)         = 6
      lseek(6, 0, SEEK_END)                   = 188645376
      lseek(6, 0, SEEK_SET)                   = 0
      read(6, "\0\0\0\0\340\5\327\1\1\0\1\0\f\3@\3\0\200\4\2008\263P\1`\262\252\1\270\261P\1"..., 32768) = 32768
      open("base/16508/1249", O_RDWR)         = 8
      lseek(8, 0, SEEK_END)                   = 1073741824
      open("base/16508/1249/1", O_RDWR)       = -1 ENOTDIR (Not a directory)
      open("base/16508/1249/1", O_RDWR|O_CREAT, 0600) = -1 ENOTDIR (Not a directory)
      futex(0x7ff80e53f620, FUTEX_WAKE_PRIVATE, 2147483647) = 0
      futex(0x7ff80e756af0, FUTEX_WAKE_PRIVATE, 2147483647) = 0
      open("/usr/share/locale/locale.alias", O_RDONLY) = 10
      fstat(10, {st_mode=S_IFREG|0644, st_size=2512, ...}) = 0
      
      

      We see HAWQ is treating pg_attribute as a directory while it is a file.
