AB  - We analyse the Planck full-mission cosmic microwave background (CMB)temperature and E-mode polarization maps to obtain constraints on primordialnon-Gaussianity (NG). We compare estimates obtained from separabletemplate-fitting, binned, and modal bispectrum estimators, finding consistentvalues for the local, equilateral, and orthogonal bispectrum amplitudes. Ourcombined temperature and polarization analysis produces the following results:f_NL^local = -0.9 +\- 5.1; f_NL^equil = -26 +\- 47; and f_NL^ortho = - 38 +\-24 (68%CL, statistical). These results include the low-multipole (4 <= l < 40)polarization data, not included in our previous analysis, pass an extensivebattery of tests, and are stable with respect to our 2015 measurements.Polarization bispectra display a significant improvement in robustness; theycan now be used independently to set NG constraints. We consider a large numberof additional cases, e.g. scale-dependent feature and resonance bispectra,isocurvature primordial NG, and parity-breaking models, where we also placetight constraints but do not detect any signal. The non-primordial lensingbispectrum is detected with an improved significance compared to 2015,excluding the null hypothesis at 3.5 sigma. We present model-independentreconstructions and analyses of the CMB bispectrum. Our final constraint on thelocal trispectrum shape is g_NLl^local = (-5.8 +\-6.5) x 10^4 (68%CL,statistical), while constraints for other trispectra are also determined. Weconstrain the parameter space of different early-Universe scenarios, includinggeneral single-field models of inflation, multi-field and axion fieldparity-breaking models. Our results provide a high-precision test forstructure-formation scenarios, in complete agreement with the basic picture ofthe LambdaCDM cosmology regarding the statistics of the initial conditions(abridged).
