The Shell lost the inverted comma in a nested ssh command

Hi,

i want use this Comand for my psql request


Code:
sh ssh -o StrictHostKeyChecking=no rootatemailaddress.de sudo psql -U postgres -c "select pg_terminate_backend(pid) from pg_stat_activity where datnam=\'$DB\';"'"



but the shell lost the inverted comma for datnam=\'$DB\'. The request deliver datnam=DB1 but for the psql request i need datnam='DB'. Where is my mistake? The psql comand need the inverted comma left and right from the $DB variable.

extract_font_range(3alleg4)					  Allegro manual				       extract_font_range(3alleg4)

NAME
extract_font_range - Extracts a range of characters from a font. Allegro game programming library. SYNOPSIS
#include <allegro.h> FONT *extract_font_range(FONT *f, int begin, int end) DESCRIPTION
This function extracts a character range from a font and returns a new font that contains only the range of characters selected by this function. You can pass -1 for either the lower or upper bound if you want to select all characters from the start or to the end of the font. Example: FONT *myfont; FONT *capitals; FONT *fontcopy; ... /* Create a font of only capital letters */ capitals = extract_font_range(myfont, 'A', 'Z'); /* Create a copy of the font */ fontcopy = extract_font_range(myfont, -1, -1); ... destroy_font(capitals); destroy_font(fontcopy); RETURN VALUE
Returns a pointer to the new font or NULL on error. Remember that you are responsible for destroying the font when you are finished with it to avoid memory leaks. SEE ALSO
